Question 255950: write a linear equation in y-intercept form
(2,4), slope =2
(5,4) slope =-2
(5,-7) slope =3
Find th slope
(1, -3) (8,5)

Remember that if you have a slope m and a point (x1,y1), the equation for the line is:
y-y1=m(x-x1)
So for the first problem we have m=2 and (x1,y1)=(2,4). So we have:
y-4=2(x-2)
y-4=2x-4
y=2x
The next two are similar, so this should help you complete that. For the question about slope, if you have two points (x1,y1) and (x2,y2) the slope is:
