Question

in y=mx+b how do you find b?

Answer 1

y-intercept

Answer 2

b = y - mx

Answer 3

if they gave u a point u would plug in the values for x and y then solve

Answer 4

for b

Answer 5

move the mx to other side m will be neg slope and b will be y=intercept

Answer 6

well right now i have slope was (-12/7) and points are (-3, 4) and (4, -8)

Answer 7

b = y - mx....

substitute all known values x-coordinate, y-coordinate and m-slope into the right side of the equation then evaluate....

b = y-intercept

Answer 8

subsititute one of the points for x and y in the equation...

Answer 9

for example 4 = -3(-12/7) +b solve for b

Answer 10

\[b = 4 - \frac{-12}{7}(-3)\]

Answer 11

\[b = -\frac{8}{7}\]
