Question

how do i graph a mx+b

Answer 1

Okay, so do you know what the variables represent?

Answer 2

Y=mx+b M in this equation is the slope while B is the y intercept

Answer 3

Let me first exaplain the y intercept

Answer 4

Lets say B is 5 so Y = MX + 5 5 would be the y intercept

Answer 5

Lets say this is our graph

Answer 6

Where do you think the y-intercept would be?

Answer 7

Ax +By + C = 0 ( Standard equation )

y = mx + b ( Slope y-intecept)

y - b = mx

(1/m)y - (b/m) = x

let x axis intercept = a

a = -b/m


to graph an equation find

b from the given y = mx + b equation
calculate a = -b/m

now let's say you got b = 2 , a = -2/-1 = 2
