Question

Given the point (4, 5) and the slope of 6, find y when x = 24.

Answer 1

plug in m = 6, x = 4 and y = 5

then solve for b



y = mx+b

y = 6x + b

5 = 6*4 + b

...
...
...

b = ??

Answer 2

@jim_thompson5910 confused.. my answer choices are 118

Answer 3

don't worry about the final answer, let's focus on solving for b first

5 = 6*4 + b

5 = 24 + b

b = ??

Answer 4

@jim_thompson5910 -19

Answer 5

so y = mx+b turns into y = 6x - 19

Answer 6

now plug in x = 24

y = 6x - 19

y = 6*24 - 19

y = ???
