Question

What is the equation of a line passing through (3, 4) and having a slope of -5?

Answer 1

@jigglypuff314

Answer 2

slope intercept form or point slope form?

Answer 3

slope intercept

Answer 4

slope-intercept form: y = mx + b
when m = slope and b = y-intercept

so you can get y = -5x + b temporarily plug in (3,4) to solve for b

Answer 5

wait so y=-5x+3?

Answer 6

I'm confused

Answer 7

4 = -5(3) + b solve for b

Answer 8

b=19

Answer 9

then plug it back into y = -5x + b

Answer 10

so the final answer is y=-5x+19 ?

Answer 11

yes :)

Answer 12

thankss!!!!
