Question

Given the two points: (0,6) and (6,18), write the equation of the line.

y = 2x + 6
y = 1/3x + 6
y = 3x + 6
y = 1/2x + 6

Answer 1

Y=2x+6 We know the y intercept is +6 so we still can’t eliminate any of the options. We know it can’t be 1/3x or 1/2x because the y value is greater than the x value. (6)(2)+6=18
