Question

Determine the slope of the line passing through the points (7,-1) and (-8,2) .

Answer 1

\[m=\frac{\Delta y}{\Delta x}\]From one point to another, how does the y value change? From this same point to the other, how much does the x value change? This ratio is your slope.

Answer 2

u can take both ys and subtract them from the s as a fraction...

Answer 3

you need the formula y2-41/x2-x1 or here it would be 2-(-1)/(-8)-7
