A line passes through the point. (4, -7) and has a slope of 5/2

blagie [28]

t p = through point

s = slope

$y - y(t \: p) = (s) \times ( \: x - x(t \: p) \: ) \\$

$y - ( - 7) = \frac{5}{2} \times (x - 4) \\$

$y + 7 = \frac{5}{2} \times (x - 4) \\$

$y + 7 = \frac{5}{2}x - \frac{5 \times 4}{2} \\$

$y +7 = \frac{5}{2}x - \frac{20}{2} \\$

Subtract both sides -7

$y = \frac{5}{2}x - 10 - 7 \\$

$y = \frac{5}{2}x - 17 \\$

And we're done....
