Draw a graph and plot the following lines on the graph. The lines passes through the point (-2,7) and has a y-intercept of 4. Find its slope. Does this line pass through the point (8,-8).
**
Equation of a line: y=mx+b, m=slope, b=y-ntercept
For given line:
7=m*-2+4
-2m=3
m=-3/2
Equation: y=-3x/2+4
plug in coordinates of point (8,-8)
-8=-3*8/2+4
-8=-12+4
-8=-8
This line passes through the point (8,-8).
