Question

Write an equation for points (0,2) and (4,0). In point slope form, and slope intercept form.

Answer 1

Use the formula Y2-Y1 / X2-X1 to find the slope of the equation

Answer 2

I got -1/2 for the slope. Then what do I do?

Answer 3

Ok that's right then use any one of the two points and make an equation in thif form y=mx+b

Answer 4

so basically you just sub in the slope as ( m= -1/2)

Answer 5

I got y= -1/2x+2

Answer 6

and then use any two points to find out the b value in the equation above

Answer 7

ok

Answer 8

so then you are done. Just need to rearrange the equation in point slope form which is y – y1 = m(x – x1)
