Question

What is the slope of the line through (-9, 6) and (-6, -9)?

Answer 1

The answer is C, you use the equation for slope, m=y-y/ x-x . I used to get really confused by these but what I found easy was writing out the two points and labling them (x1,y1) and (x2,y2). Don’t get confused by the numbers that follow x and y , they aren’t exponents they are just so you know what goes where. Hope this helped
