Explanation:
The two lines cross at this location. This (x,y) point is located on both lines at the same time. A point on a line satisfies that said equation.
----------
An algebraic way to confirm the answer is to apply substitution to the first equation like so:
y = x+4
6 = 2+4
6 = 6
Repeat for the second equation
y = -0.5x+7
6 = -0.5*2+7
6 = -1+7
6 = 6
We end up with true equations for both cases, so this algebraically confirms (2,6) is the solution to the given system.

Graph y+6=45(x+3) using the point and slope given in the equation. Use the line tool and select two points on the line.
Answers
Answer:
Step-by-step explanation:
We are given the equation y+6 = 45(x+3).
On simplifying the equation we get,
y+6 = 45x + 45×3
i.e. y+6 = 45x + 135
i.e. y = 45x + 129.
Now, x = 0 gives y = 129 and y = 0 gives x = -2.867.
The general form of a straight line is given by y = mx + c, where m is the slope and c is the y-intercept.
So, on comparing, the slope of given equation is m = 45.
Plotting this straight line y = 45x + 129 on the graph gives the following figure.
The two points selected on the graph are (0,129) and (-2.867,0).

Which pairs of points have lines passing through them with a slope of 2/3?
Answers
Answer:
(0,0) and (3,2)
(1,5) and (4,7)
(-2, -2) and (4, 2)
Step-by-step explanation:
The first option will have a slope of 3-0 over 2-0, which is 1.5, which is incorrect.
The second option will have a slope of 2-0 over 3-0, which is 2/3, and is correct.
The third option will have a slope of 7-5 over 4-1 which is 2/3, and is also correct.
The fourth option has a slope of 2+2 over 4+2, which is 2/3, and is correct.
The fifth option has a slope of -30-30 over -20-20, which is also 1.5, and is incorrect.
Therefore, the middle three options are correct.
Pairs of points have lines passing through them with a slope of 2/3 are (0,0) and (3,2), (1,5) and (4,7) , and (-2,-2) and (4,2)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
We need to find pairs of points have lines passing through them with a slope of 2/3
(0,0) and (2,3)
m=3/2 which is not equal to 2/3
Hence it is not passing through these points.
(0,0) and (3,2)
m=2/3 which is equal to 2/3
it is passing through (0,0) and (3,2)
(1,5) and (4,7)
m=7-5/4-1=2/3 which is equal to 2/3
it is passing through (1,5) and (4,7)
(-2,-2) and (4,2)
m=2+2/4+2=4/6=2/3 which is equal to 2/3
it is passing through (-2,-2) and (4,2)
(20,30) and (-20, -30)
m=-30-30/-20-20=-60/-40=3/2
Hence pairs of points have lines passing through them with a slope of 2/3 are (0,0) and (3,2), (1,5) and (4,7) , and (-2,-2) and (4,2)

What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answers
Answer:
[tex]y=-\frac{1}{4}x\\[/tex]
Step-by-step explanation:
The slope is calculated by "up ÷ across".
= -1 ÷ 4
= [tex]-\frac{1}{4}[/tex]
The y-intercept is just 0 (because the line meets at the y axis at 0).
So, using [tex]y=mx+b[/tex] (where m = slope and b = y-intercept),
[tex]y=-\frac{1}{4}x+0[/tex]
but the '+0' is unnecessary so we just say [tex]y=-\frac{1}{4}x[/tex]
If 4 gallons of milk cost $16.24, how much would 7 gallon of milk cost
Answers
Answer:
$28.42
Step-by-step explanation:
First let's calculate the cost per gallon.
We can do this by simply dividing the cost of 4 gallons by 4
1 gallon of milk cost 16.24/4 = 4.06
We want to find the cost of 7 gallons.
We can easily do this by multiplying the cost of one gallon by 7
7 gallons of milk cost 7 * 4.06 = $28.42
