## anonymous one year ago Use the given conditions to write an equation for the line in point-slope form. Passing through (-5, -7) and (-8, -6)

calculate the slope by using those two points first...

2. DanJS

$(y-y _{1}) = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }*(x - x_{1})$

3. DanJS

Use those two points, (x1 , y1) and (x2,y2), plug in there

Slope = -0.3 θ = 161 ΔX = -3 ΔY = 1

Well first find the slope, using the following formula: $m = \frac{ y_{2}-y _{1} }{ x _{2}-x _{1} }$ where your coordinates represent $(x_1,y_1)~~\text{and}~~(x_2,y_2)$ Once you manage to get that, plug in m and your first coordinates in the point - slope form: $y-y _{1}=m(x-x _{1})$ do some little algebra and eventually you will have slope - intercept form $y=mx+b$
