#1,2,3, just use the formula for slope. Vertical change divided by horizontal change.
#4, simply plug into point-slope equation form.
and simplify this.
Refer to the given point and slope to help in graphing.
---
The format for point-slope form is for a line containing point (u,v) and having slope m, the equation can be shown as y-v=m(x-u).

ANSWER: Slope is 2/3.
The others are done the same way.
.
4. (-3,-1),m=-1/5
Using slope intercept form:
y=mx+b
y=(-1/5)x+b Put in values for point given and solve for b.
-1=(-1/5)-3+b
(-5/5)=(3/5)+b
(-8/5)=b Substitute this for b to get the equation.
(b is the y intercept, so one point is (0,(-8/5)).
.
y=(-1/5)x+(-8/5) Set y=0 to get x-intercept.
.
0=(-1/5)x+(-8/5)
(8/5)=(-1/5)x
-8=x The x-intercept is (-8,0)
Graph the two points and draw a straight line through them.
