write equation of line w/ slope m = 4, y-int b = 8

[Ninigirl750]

Write the equation of a line with the given slope and y-intercept:

slope m = 4
y-intercept b = 8

 

[arthur ohlsten]

equation of a straight line
y=mx+b

let m=4,b=8 substitute
y=4x+8 answer

On a graph how would it kinda go?

 

[arthur ohlsten]

y=4x+8 a straight line
two points determine a straight line. let us define two points

let x=0 then y=8 because y=4[0]+8
let x=1 then y= 12 , because y=4[1]+8

plot the two points 0,8 , and 1,12
draw a straight line thru these two points
