After you combine like terms you will get 5p - 9m.
-3p + 8p is the same thing as 8p - 3, so you get 5p.
-2m + (-7m) is -9m
-3p and 8p are like terms.
-2m and -7m are also like terms.
1. Slope-intercept form is y=mx+b, where m=slope and b=y-intercept. To answer this question, plug in the values they have given you.
y=mx+b
y=1/4x-5
2. To write an equation in slope-intercept form when given two points, use m=y2-y1/x2-x1
Remember: in an ordered pair, x comes first then y.
Plug the y- and x-values in. So, y2=6, y1=2 and x2=-2, x1=9
6-(-)2/-2-9= - 4/11.
The slope of your next equation would be m= - 4/11
