$y-y_1=m(x-x_1) \\ \\
m=-\frac{5}{8} \\
(-10,-6) \\
x_1=-10 \\
y_1=-6 \\
\Downarrow \\
y-(-6)=-\frac{5}{8}(x-(-10)) \\
\boxed{y+6=-\frac{5}{8}(x+10)} \ - \ \hbox{the point-slope form} \\ \\
y+6=-\frac{5}{8}(x+10) \\
y+6=-\frac{5}{8}x-\frac{50}{8} \\
y=-\frac{5}{8}x-\frac{50}{8}-6 \\
y=-\frac{5}{8}x-\frac{25}{4}-\frac{24}{4} \\
y=-\frac{5}{8}x-\frac{49}{4} \\
\boxed{y=-\frac{5}{8}x-12 \frac{1}{4}} \ - \ \hbox{the slope-intercept form}$

In triangle △WXY, XY ≅ WX and m∠X=38 Find m∠W

allsm [11]

Answer:

$71^{\circ}$

Step-by-step explanation:

Since two sides of the triangle are equal in length, we can conclude that $\triangle WXY$ is an isosceles triangle. With this information, we can draw an isosceles triangle to find $m\angle W$ . Since the base angles of an isosceles triangle are equal, we can solve for $m\angle W$ :
