Find the y-intercept of the line that passes through the given  pair of points:  (-2, -3), (4, 3)

• b = 3

• b = 2

• b = 1

• b = -1

Write the y-intercept for the function that passes through the points (−2, 6) and (2, 7). Change it to a decimal.

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.
