Answer:
Remember the slope formula:
m= y2-y1/x2-x1

Find the function value: f(0.5) if f(x) = 8x - 12
Answers
f = 0.5
0.5(x) = 8x -12
0.5x= 8x -12
subtract 8x from both sides
-7.5x = -12x

What are the slope and the y-intercept of the graph of the linear function shown on the grid?
Answers
Answer:
C
Step-by-step explanation:
Slope=rise/run
Y intercept is the where the line hits the y axis which is -1.5
Answer:
Slope: -1/4
y-intercept: -1.5
Step-by-step explanation:
First you do rise over run meaning you from the point (-2,2) you rise up 2 to reach the x axis which is where point -6,0 so you rise 2 points and run 6. since the line is negative it becomes -1/4 and y-intercept is where the line first touches the y-line which is -1.5. I hop this helps!

What value of Y makes the equation true ?
Answers
Answer:
y = -5/2 or -2.5
Step-by-step explanation:
3y + 4 = -y - 6
add y to both sides
4y + 4 = -6
subtract 4 from both sides
4y + 4 - 4 = - 6 - 4
4y = -6 - 4
4y = -10
divide both sides by 4
4y/4 = -10/4
y = -10/4
y = -5/2 or -2.5

Answers
Answer:
8) the ordered pair is a solution, 9) the ordered pair is not a solution
Step-by-step explanation:
8) if you plug in the values of x into the equation, which is 7, 7+9 equals to 16, which is the y value in the ordered pair
9) the same is for this question, if you plug in the x value into the equation, which is 5, 2(5)+8 is equal to 10+8 which is equal to 18. This isn't equal to the y value in the ordered pair
Answer:
8.) yes it is a solution because if plug in 7 for x and 16 for y you get 16=7+9 which equals 16
9.) No it is not a solutions because if you plug in 28 for y and 5 for x you 28=2(5)+8 and then when you multiply the 2 and the 5 you get 28=10+8 and 10+8 equals 18 and 28 and 18 are not equal
