MULTIPLE CHOICE QUESTION

1 min • 1 pt

A line passes through the coordinates (2,6) and (3,3). What is the y-intercept of this line?

b = -9

b = -6

b = 6

b = 12

Answer explanation

To find the y-intercept, insert the value for slope in for m and one of the coordinates in for x and y. Use the equation y = mx + b and solve for b.
