Question

write the equation for this line in slope intercept form.y= ? × + __ a) -4 b) 2c) -2 d) -1/2

Answer 1

we know that

the equation in slope intercept form is equal to

y=mx+b

In this problem

we have

b=-4 ------> because the y-intercept is (0,-4)

Find the slope

we need two points

we take

(-2,0) and (0,-4)

so

m=(-4-0)/(0+2)

m=-4/2

m=-2

therefore

y=-2x-4
