-3/2
Step-by-step explanation:
There are three steps in calculating the slope of a straight line when you are not given its equation.
Step One: Identify two points on the line.
Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
Step Three: Use the slope equation to calculate slope.
(x1,y1) → (2,10) and (x2,y2) → (4,7)7 - 10 = -34 - 2 = 2Slope: -3/2
