Question

Use the form y=mx b for linear equations.Write the equation for the following relation.C = {(x, y): (6, 15), (8, 21), (10, 27), . . .}

Answer 1

Y= 3x-3. You need to figure out what x will be when y=0. This is your "b" or y-intercept. This happened to be -3. Then you need to figure out the rate of change which is 6/2 which simplifies down to 3. 3 will be your "m" or the slope. I hope this helps!
