Question

Suppose a line has a slope of 2. If a point on the line is (5, 9), which point would also be on the line?

Answer 1

formula for slope?

Answer 2

y=mx+b

Answer 3

use point slope form:
\[y-y_1=m(x-x_1)\]
then replace m with your slope number
replace your point (x1,y1) with the point you are given that is on the line

now replace x with any value and solve for y (this will give you another point on the line)

Answer 4

or you could turn the point slope form into slope intercept form
and use the other point as the y-intercept

Answer 5

either way

Answer 6

@freckles can't we use slope = rise over run....so that we can directly get the point

Answer 7

yeah you can do that too
