How do you solve a y=mx+b equation if x is unkown?
example -
y = 1.29x+2
How do I solve that? Please make sure to explain :) thanks!

Answers

Answer 1

Answer

Y= 2 x= -0.645

Step-by-step explanation:

you basically plug 0 into x and y

y=1.29(0)+ 2

y=2

0=1.29x+ 2

Answer 2

Answer:

Okay so "y = mx+b is a linear equation that represents a line on a graph; m represents the slope of the line and b is the y-intercept (The y-intercept of this line is the value of y at the point where the line crosses the y axis.)

In y = 1.29x+2, 1.29 is equal to m, so that is your slope.

The 2 is equal to the b so your y-intercept is 2.

Here's a  graph to better understand it :)
