Y=mx+b (x,y) m= slope b= y-intercept slope is y2-y1/x2-x1 find your slope and then put a coordinate pair in your equation (y=mx+b) then solve to get a number for b. Try it using the coordinates (66,64) and (68,66) x1 y1 x2 y2
Try it and put your answer in the comments and I will tell you if you are right! The only way to learn is to try and get guidance, but not answers just given to you!
Our goal is to get y by itself We will first add 3x to both sides to get -5y = 3x - 15 We will then divide both sides by -5 to get y by itself which becomes y = -3/5x + 3
