You can put this solution on YOUR website! 1# question: find the equation of the line, find the slope and y-intercept, plot the points and line.
1. (5,20), (15,5)
2. (14,4), (15,2)
==============================
We first will find th slope;
Now lets find y-intercept, which in the slope-intercept form y=mx+b, the b=y-intercept;m=slope
We take either one of the points, and plug them into the equation;
 , now we solve for b;
like denominators to add whole number with fraction;
So our equation will be;
-----------------------------------
(14,4), (15,2)
So our equation is;
y=-2x+32
=======================================
2# question: find the slope and y-intercept, plot the line.
1. y= 6x + 3
2. y=2x + 10
3. y + 5 = x
------------------------
1. s=6, y-intercept=3
2. s=2 y-intercept=10
-----------------------------------------------
3.
Let's first put this in slope-intercept form;
Multiply each side by 4,
y+5=4x
then subtract 5 from each side;
y=4x-5
Now graph:
4. 
Let's do the same here;
multiply each side by -5;
y-10=-5x
subtract 10 from each side;
y=-5x+10
