Question 714813: Need the steps and an explanation on how to get to the answer
Slope= 4, passing through (1,3)

Two ways to do it.

Method 1: Use the slope-intercept formula

y = mx + b

Substitute 4 for m, 1 for x and 3 for y

 3 = 4(1) + b
 3 = 4 + b
-1 = b

Substitute just -1 for b and 4 for m in y = mx + b,
only this time don't substitute for x or y but leave 
them variable:

y = 4x - 1

----------------------

Method 2:  Use the point-slope formula:

y - y1 = m(x - x1)

where (x1,y1) = (1,3) and m=4

y - 3 = 4(x - 1)
y - 3 = 4x - 4
    y = 4x - 1
