Complete the point-slope equation of the line through (2,3)(2,3)left parenthesis, 2, comma, 3, right parenthesis and (7,4)(7,4)l
vovikov84 [41]

Answer:

y = \frac{1}{5}x +\frac{13}{5}

Step-by-step explanation:

Given

(x_1,y_1) = (2,3)

(x_2,y_2) = (7,4)

Required

Complete the equation y - 4.....

First, we need to determine the slope as follows:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{4 - 3}{7 - 2}

m = \frac{1}{5}

The equation is then calculated as thus:

y - y_1 = m(x - x_1)

This gives:

y - 4 = \frac{1}{5}(x -7)

Open bracket

y - 4 = \frac{1}{5}x -\frac{7}{5}

Add 4 to both sides

y - 4 +4= \frac{1}{5}x -\frac{7}{5} + 4

y = \frac{1}{5}x -\frac{7}{5} + 4

y = \frac{1}{5}x +\frac{-7+20}{5}

y = \frac{1}{5}x +\frac{13}{5}

Divide the 10 by 4, which makes the x be 2.5. You can check it by multiplying 4 by 2.5, which will give you 10.
