85 + 90 = 175

180 - 175 = 5 (the missing angle not x)

angles on a straight line add up to 180 degrees

180 - 5 =175

1. Find the slope of the line that passes through the points (-3, -5) and (3, 2).

Veseljchak [2.6K]

$(-3, -5), \ \ (3, 2) \\ \\ Slope Formula : \\ \\ m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\ \\m=\frac{ 2-(-5)}{ 3-(-3)}\\\\ m=\frac{ 2+5}{ 3+3}\\\\m=\frac{7}{6}$
