Question

PLEASE HELP

find b in y=mx+b
the points are (4,2) and (11,18)
PLEASE SHOW YOUR WORK
thank you!!

Answer 1

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.
