Answer:

b = -50/7

Explanation:

1. The formula to find y-intercept (b) given two points is
b = y_1 - m * x_1, but let's first find the slope using
(y_2-y_1)/(x_2-x_1).


  • (18-2)/(11-4)

  • (16)/(7)

2. Now that we have the slope, let's use the formula for finding the y-intercept.


  • b = 2 - (16)/(7) *4

  • b = 2-(64)/(7)

  • b = 2 - 9(1)/(7)

  • b = -7(1)/(7)

  • b = (-50)/(7)

Therefore, the y-intercept is -50/7.
