(32,22) (48,17) (64,12) What is the y-intercept of the line?

the y-intercept of the line is 32

Step-by-step explanation: Detrermine the slope of the line by finding the differences in y values divided by the differences in x values.

12- 17 = -5    17-22 = -5   so  Rise is  -5

64 - 48 = 16   48 - 32 = 16     so Run is 16

Use the slope formula to compute y-intercept   y = mx + b  

Substitute given values in he slope formula to compute  b

 divide 32/16 = 2

22 = -5(2) + b    22 = -10 + b

22 + 10 = 32    32 is the y-intercept

   divide 48/16 = 3

17 = -5(3) + b     17 = -15 + b

17 + 15 = 32   again, 32 is the y-intercept
