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

well first is y=-2x+b
to find b substitute the coordinates into the equation.

Answer 2

12=-2*8+b
b=28
y=-2x+28

Answer 3

slope is the cooeficent with the x

Answer 4

thxs ca u help me with some more please?

Answer 5

yes

Answer 6

also welcome to openstudy!!!

Answer 7

What is the slope-intercept form of the function that contains the points (3, 1) and (2, 9)?



y = x +

Answer 8

oh thxs:)

Answer 9

slope formula is (y1-y2)/(x1-x2)=(9-1)/(2-3)=-8
slope is -8. y=-8x+b 1=-8*3+b b=25---> y=-8x+25

Answer 10

so this the y=-8x+25 answer:)?

Answer 11

yes
