Question

Find the slope of the line that contains the following pair of points (4,3), (6,7)

Answer 1

The equation of the line is 2x-5. The gradient is the number that comes before the x, so the slope is 2.

Answer 2

Use the point slope formula $\frac{ y_{2}- y_{1} }{ x_{2} - x_{1} }$ plug in your numbers where 4=x1, 3=y1, 6=x2, and 7=y2 $\frac{ 7-3}{ 6- 4 }$ $\frac{4}{2} }$ which equals 2
