Question

Hey! can someone give me the y=mx + b for:

goes through the points (6, 2) and (5, 4)
lmk if you need better clarification!

Answer 1

y=-2x+14

Explanation:

use point slope

y-y1=m(x-x1)

and m= y2-y1

x2-x1

m= 4-2

5-6

m=2/-1

then use the 1st formula to plug everything in

y-2=-2(x-6)

then distribute the 2 on the right side

y-2=-2x-2×-6

-2×-6 is 12 since a negative times a negative is positive

y-2=-2x+12

then to get y alone we have to get everything on the right side of the = sign, so the opposite of subtraction is addition, lets add 2 to the right

y-2=-2x+12

+2. +2

y=-2x+14
