Question

What is the equation of the lne that passes through points (5,4) and (-2,0)?

Answer 1

rise/run

Answer 2

first find slope

Answer 3

then use y=mx+b

Answer 4

subsitute slope

Answer 5

and then find y intercept

Answer 6

Call point (5, 4) = (x1, y1), and call point (-2, 0) = (x2, y2)

Slope = m = (y2 - y1)/(x2 - x1)

The equation of the line is:
y - y1 = m(x - x1)

Answer 7

he has point slope form

Answer 8

both can be used though

Answer 9

ok. thank u. :)

Answer 10

can u check if im doing it right because i feel like i messed up somewhere?

Answer 11

Sure. Show what you did.

Answer 12

i found the slope using m= Y2-Y1/X2-X1. i got 4/7

Answer 13

Correct, m = 4/7

Answer 14

then i plugged it in y=mx+b.
so now i have y=4/7x+b.

Answer 15

i plugged in point (5,4) sonow i have 4=4/7x5+b

Answer 16

then i got 4=20/7+b.thats were im not sure if im right.

Answer 17

Correct
