Question

Find the equation of a line through (2,3) and (-4,5).

Answer 1

1) find slope ...(y2-y1)/(x2-x1)

2) plug in slope and one of the two points into the point/slope form. Point/slope form is: y-y1=m(x-x1)

THerefore, for this problem m(slope) = -1/3, and I will choose the point (2,3) to plug into y-y1= m(x-x1)

3) y-3=-1/3(x-2)

4) Now, solve for y...
