Solve for r:
r over 8.45 = 15.2

1. r = 128.44
2. r = 23.65
3. r = 1.79

I’m back
r over 8.45 = 15.2
r = 128.44

The answer is 3) 1.79

You do 15.2/8.45
And you get 1 135/169 then you approximate it and that gives you 1.79

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
