Find the slope of the line through each pair of points, then graph
(19,-16),(-7,-15)
:
x1=19, y1=-16
x2=-7, y2=-15
:
Find the slope using the formula: m = %28y2+-+y1%29%2F%28x2-x1%29
m = %28-15+-+%28-16%29%29%2F%28-7+-+19%29
m = %28-15+%2B+16%29%2F-26
m = 1%2F-26
:
Use the point slope formula: y - y1 = m(x - x1)
y - (-16) = -1%2F26(x - 19)
y + 16 = -1%2F26x + 19%2F26
y = -1%2F26x + 19%2F26 - 16
y = -1%2F26x + 19%2F26 - 416%2F26
y = -1%2F26x - 397%2F26
:
Graph this in the above equation by substitution with the given values, it should look like this
+graph%28+300%2C+200%2C+-20%2C+20%2C+-20%2C+5%2C+%28-1%2F26%29x-%28397%2F26%29%29+
