The first thing you should know is that the slope of the line that passes through two points, by definition is given by:
 m = (y2-y1) / (x2-x1)
 Substituting the values we have:
 m = (76-70) / (28-30)
 m = -3
 answer:
 the slope of the line between points a and b is
 m = -3

What is the equation graphed in this figure?
laiz [17]
The correct answer is D. If you look at the equation you can see that the line crosses at the points (1,5) and (-2, -4). Use this set of ordered pairs to find the slope. (-4-5)/(-2-1) = (-9/-3) = 3 The use the point-slope formula and fill in the ordered pair (1,5) with the slope. y - 5 = 3( x - 1)
