Question

Does anyone know how to do this?

Answer 1

Hello!

The slope of the first line is -3.

The y-intercept of the second line is -4.

How did I identify the slope & y-intercept?

Let me share my "secret"

Well, both equations are written in slope-intercept form (y=mx+b)

where m = slope & b = y-intercept.

Now you know ;-)

Anyway, the new line should have the same slope as the first line (-3)

And the y-intercept of the second line is -4.

So the equation is

y=-3x-4

Hope everything's clear!

Answer 2

y = - 3x - 4

Explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 10 - 3x = - 3x + 10 ← is in slope- intercept form

with slope m = - 3

y = - 6x - 4 ← is in slope- intercept form

with y- intercept c = - 4

then equation of required line is

y = - 3x - 4
