Question

The equation y=mx+b goes through the points (4,8) and (-6,3).

Answer 1

Y= 1/5x+36/5
Y=mx+b. To find M (slope) all u do is set up: m=y^2-y^1/x^2-x^1 once u find your answer, replace m with the answer u get. To find b all u need to do is use one of the points given already, & set the y point, equaled to the sander you just got for m, multiplied by the x (replace the x) with the x given in the points I chose+b for example: 8=1/5(4)+b then multiply then subtract on both sides to get b alone
