Question

What is the slope of aline that is parallel to the line that passes through (1,2) and (3,6)?

Answer 1

Use the formula to find your slope.

\[m = \frac{ x1 - x 2 }{ y1 - y2 }\]

Answer 2

Slope would be change in y per change in x, i.e.:
\[ \quad m = \frac{y_2 - y_1}{x_2 - x_1}\]
So, the reciprocal of the above.
