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

write in slope-intercept form
:
1.a slope -4 and y intercept of 3/4
The slope intercept form of a line is: , where m=slope and b=y-intercept.
In this case, m=-4 and b=3/4, so the equation is:

:
2.a line passing through (-3,-6) with slope 9/5
When given a point and a slope, we can find the equation of the line with the point-slope formula: , where m=slope and (x1,y1)=given point
In this case, m=9/5 and (x1,y1)=(-3,-6)

:
3.line that passes through (5,2) and m=9/5
You have a point and a slope, use the point slope formula that we used for the last one:
m=9/5 and (x1,y1)=(5,2)

Happy Calculating!!!
