Answer:
Step-by-step explanation:
Point-slope form of the equation of a straight line is:
(1)
The two points given in the problem are:
So, the slope of the line is given by:
And substituting into eq.(1), we find:
slope = 3
Up 3 over 1, on the grid so,
3/1 = 3
n=80
n/4=20
(n/4=20)4 . to get rid of the denominator u multiply by 4 on both sides
