Question 399302: Find an equation of the line with the given slope and y-intercept : Slope = -7, y-intercept = (0, -13)
This is what I tried:
y = mx + b
-13 = -7(0) + b
-13 = 0 + b
-13 -0 = b
-13 = b
so y-intercept is (0,-13)
and the given answer is y = -7x -13, and I also don't know how to graph with this problem. Thank you
