Answer:
Since this is a school problem, I'll give a hint.
Explanation:
The equation in finding a line is y=mx+b.
Y= the y coordinate.
M=slope
x= x coordinate
b= y intercept (which is when x is o.)
Slope equations:
y2-y1/x2-x1
When I say "y2" or "y1", I mean find 2 different coordinates (helps if their intercepts), and use the x, and y's.
Hope this helps!
