Mathematics: Turn the points (3, -1) (-3, 5) into slope-intercept form. i found the answer online, but i need on how to get it. (the answer is y= -x + 2 just for reference)

$\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{-1})\qquad (\stackrel{x_2}{-3}~,~\stackrel{y_2}{5}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{5-(-1)}{-3-3}\implies \cfrac{5+1}{-3-3}\implies \cfrac{6}{-6}\implies -1 \\\\\\ \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-1)=-1(x-3) \\\\\\ y+1=-x+3\implies y=-x+2$

Mathematics

"AB=BC" Meaning this is an isoceles triangle

Thus ∠C is an angle Identical to ∠A
And given the rule of thumb; "every angle on a triangle. must add up to 180°"

∠A + ∠C = 130°
180° - 130° = ∠B

∠B = 50°
