Question

using the formula y=mx=b, find the equation of the line determined by the two points (3,-8) and (9,5)

Answer 1

First you have to find the slope between the two points

Answer 2

Do you know how to find slope?

Answer 3

(y2-y1)/(x2-x1)

Answer 4

yes but i think it wants us to plug in the -8 in for y and 3 in for x, the the next set for the next equation

Answer 5

not yet, first you have to find slope

Answer 6

slope is 1/2?

Answer 7

y=1/2x+b
now you plug in your y and x value to find b

Answer 8

of either point

Answer 9

would it be -8?

Answer 10

-8=1/2(3)+b
-8 - 3/2=b

Answer 11

the answer was 13/6x+-29/2
