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.
We can use the points (-4, -1) and (0, -3) to solve.
Formula: y2-y1/x2-x1
= -3-(-1)/0-(-4)
= -2/4
= -1/2
Best of Luck!
