Find the equation of a line that has the same slope ask why equals 10-4x and the same Y intercept is why equals -9x-8

Alborosie

Answer:

$y=-4x-8$

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

1) Find the slope of the given line $y=10-4x$

The slope is $m=-4$

2) Find the y-intercept of the given line $y=-9x-8$

The y-intercept is $b=-8$

therefore

The equation of the line with

$m=-4$

$b=-8$

is equal to

$y=-4x-8$
