use the slop and y intercept to write an equation of each line in standard form

y=mx+b is slope intercept form, where m=slope and b=y-intercept.
For example, if slope is 3 and there is a y-intercept at y=3, then the equation is: y=3x+3.
If they want point slope form then it is y1-y2=m(x1-x2).

okay soo
y = mx + b
y is any given y-coordinate.
m is the slope of the line.
x is any given x-coordinate.
b is the y-intercept of the line.
you can find any of them if given the other three. so just substitute the given slope for m (ex. 3) and the y-intercept for b (ex. 7).
thus, you get the equation of a line with slope m and y-intercept b.

The equation for slope is y=mx+b. M=slope and B=y intercept

slope(m)= 2 Points (3, 1) x=3 y=1
y=mx+b
(1)=(2)(3)+b b=-5
y=2x-5!

well whats the question? n i will tell you how to do it? well its also easy, just use y=mx+b. y=the y intercept and m=slope.
