Question 1050345: I have been learning about slopes,y-intercept, and more but these 2 problems are really hard. I have tried to do it myself but i cant and i need to learn this.

Queastion: Find an equation for the line that satisfies the consitions.
1. Slope 2; passing through (4, 12)
2. Passing through (0, 15) and (5, 3)
They didnt give me a graph to use so this is really hard.

Find an equation for the line that satisfies the conditions.
1. Slope 2; passing through (4,12)
Use
y-y1 = m*(x-x1) where m = slope and (x1,y1) is the point.
y-12 = 2*(x-4)
That's it.
====================
2. Passing through (0,15) and (5,3)
Step 1 find the slope, m
m = diffy/diffx = (15-3)/(0-5)
m = -12/5
--------------
Now same as #1, using either point.
y-15 = (-12/5)*(x-0)
y-15 = -12x/5
------------
There are only a few things to remember.
The slope, m, is obvious. It's the change in y divided by the change in x.
