Question

Use the interactive tool to graph the line given the following information:     coordinates (1,–3)     slope of –2 Based on your investigation, what is the value of b for the point (0,b)?

Answer 1

The line can be written in the form y=mx+b. Plugging -2 in for m , 1 in for x, and -3 in for y, we get -3=-2*1+b=-2+b. Adding 2 to both sides, we get b=-1 and our equation turns into y=-2x-1 since y and x stay variables. Plugging it into a graphing calculator, we get in (0,b) that b = -1

Answer 2

Answer:

b=-1
