y=mx+b is the formula for linear equations

m=the slope
b=the y-intercept

They give you the formula to find the slope based on 2 known points.

To find the x-intercept, just make y 0 and solve the equation.

For the ones where they give slope and a point, just plug in the points into the equation and solve for b, which is the y-intercept.

I think that covers everything but let me know if there's something else.

If they only give you one point and the slope, for example

Slope=3
(2,5)

Then just plug 2, 5, and 3 into the y=mx+b formula and solve for b which is the only unknown value.

for your question "what if they only give 1 point and slope"

for the first question

m is the slope

y=mx+b is the answer format

m=4, x=3, y=-1

-1=(4)3+b

solve for b

-1=12+b
11=b

-1=4(3)+11
