How to do substitution

1 answer:

5 0

You solve for one variable like
y-5x=2
"y=5x+2"

9x+3y=58
and you plug it in into the other equation
9x+3(5x+2)=58

You solve for x and then plug in your answer for x into the other equation
*let's imagine x=8*
then:
y-5(8)=2
and solve for y

✫ First of all, Slope-intercept form is written as follows:-

$\longmapsto\Large\textbf{y=mx+b}$

Where:-

m = slope ;
b = y-intercept

To find:-

The equation of the line

Solving,

Replace m with -1/5 And b with -3:-

$\large\text{$y=-\displaystyle\frac{1}{5} x-3$}$
