here goes.
plot (7,1) then use the slope to find the next point
from (7,1) go four to the right and three up to(11,4)
slope=m=3/4
rise over run
Does that help?

The slope of any equation is determined by the slope formula, or m, which = , where in this case, . Since it's given that m, or the slope = , then we'll have:
3(7 - r) = 4(- 3) ------ Cross-multiplying to get rid of denominators
21 - 3r = - 12
- 3r = - 33
r = , or, r =
