Question

Write the equation of the line in slope-intercept form.

The line is parallel to y + x = 3 and passes through the point (-12, 0).

Please help i will give big points

Answer 1

The line is parallel to y + x =3

=> y = -x+3

the slope = -1

passes (-12, 0)

the equation would be :

y-0 = -1(x+12)

y = -x -12 Y=-x+12

Turn into mx+b form.

Y=-x+3

Plug in (-12,0)

0=-12+b

b=12

y=-x+12

It is negative X, because the slope has to be the same since it is paralle
