Question 64947
write in slope-intercept form 
1.a slope -4 and y intercept of 3/4
y=-4x+3/4
-------------
2.a line passing through (-3,-6) with slope 9/5
y=mx+b;
You are given x=-3,y=-6, and m=(9/5)
You need to solve for "b".
-6=(9/5)(-3)+b
-6=-27/5+b
-30/5 = -27/5+b
b=-3/5
EQUATION: y=(9/5)x-3/5
-------------------
3.line that passes through (5,2) and slope = 9/5
2=(9/5)(5)=b
2=9+b
b=-7

EQUATION:
y=(9/5)x-7
