Question

What is the slope-intercept form of the function that contains the point (8, 12) and has a slope of −2?

y = ? x + ?

Answer 1

slope is the coefficent with x
y-intersect is the second value

Answer 2

y=-2x+b
12=-16+b b=28 y=-2x+28

Answer 3

you lost me?

Answer 4

no

Answer 5

no i mean i don't understand

Answer 6

so fist write y=-2x+b
now substitute coordinates of point: 12=-2*8+b solve for b

Answer 7

b=28 so wiite y=-2x+28

Answer 8

nevermind i thought you wrote something else cause i have dyslexia sorry.

Answer 9

ok

Answer 10

Thanks!
