Find the equation of the line passing through the points 3, 3 and 4, 5

Step-by-step explanation:

The equation of a line is:

y - 3 = 2(x - 3)

Step-by-step explanation:

Please use parentheses to indicate points:   the points 3, 3 and 4, 5 should be written as (3, 3) and (4, 5).

As we move from the first point to the second, x increases by 1 and y increases by 2.  Thus, the slope of the line connecting these two points is m = rise / run = 2 / 1 = m = 2

Using the point-slope formula y - k = m(x - h), we obtain:

y - 3 = 2(x - 3)
