Question

how do you find additional points on a line with a slope of 1/2 and a given point of (7,-2)?

Answer 1

need the points not the equation

Answer 2

slope means rise over run
so your slope is 1/2, meaning for every increase of 2 in the x, the y changes by 1

so keep adding 2 to the x, and 1 to the y to get as many extra points as you want without finding the equation

first extra point is (9,-1), then (11,0) etc

you could also subtract 2 from the x and subtract 1 from the y, e.g. (5,-3)

notice finding the slope between any pair will give you 1/2

Answer 3

umhh

did you see any equation in my answer?
I gave you points, not the equation.
