Question

Find the missing value so that the line passing through the points has the given slope.

(x,9) and (1,6); m=1

Answer 1

m = [F(y2) - F(y1) ] / [[F(x2) - F(x1)] slope of a line

[9 - 6] / [x - 1] = 1 that an increase in x equals the increase in y

Obviously, x must equal 4 so 3 / 3 = 1 or when x increases by 3, y must also increase by 3 for m to equal 1
