Question

What is the equation of a line that passes through (7, -2) and has a slope of 3?

Answer 1

yo

Answer 2

Use point-slope form.

\[y - y_1 = m(x - x_1)\]

m = 3
(x1, y1) = (7, -2)

Answer 3

which "equation" of the line is appropriate?

Answer 4

first plug in the slope to your point-slope equation to get:

y=3x+b

now put in your point for x and y and solve for b

-2=21+b
b=-23

so your equation is:

y=3x-23

Answer 5

i mean slope-intercept

Answer 6

I like the:

y = mx -mPx +Py version :)

Answer 7

y = 3x -3(7) -2
