Question

Write the equation of the line given by the following graph in standard form.

3x – y = –3

3x – y = 3

–3x + y = –3

–3x – y = 3

Answer 1

we know the slope is -2 and a point is (-4,0) so y = -2x+b
so 0 = -2(-4) + b so b = -8
y = -2x-8

Answer 2

the line passes through the points (-4, 0) and (-2, -4)

then the slope of the line is m = ( -4 -0)/(-2 - -4)

m = -4/2

m = -2

the slope of the line is m = -2

so non of the listed answers fit the line

Answer 3

how can I simplify this y = -2x-8
