Find the point with y-coordinate -28 on the line through (-62, 4213) with slope -69!

 

So we can solve this for the x coordinate of the point in the slope "formula"

 

[ 4213 - -28 ] / [ -62 - x] = -69    simplify

 

4241 / - [ 62 + x ]  =  - 69       multiply both sides by  - [ 62 + x ]

 

4241 = - 69  *  - [ 62 + x ]

 

4241 =  69  *   [ 62 + x ]

 

4241 =  4278 + 69x

 

-37 = 69x

 

-37/69   = x

 

So the point is (-37/69, -28)
