Line t passes through points (2, 2) and (7, 10). Line u is parallel to line t. What is the slope of line u?
The slope of line t can be found using the formula:
\(m = \frac{{y_2 - y_1}}{{x_2 - x_1}}\)
Plugging in the coordinates (2, 2) and (7, 10):
\(m = \frac{{10 - 2}}{{7 - 2}} = \frac{8}{5}\)
Since line u is parallel to line t, it will have the same slope. Therefore, the slope of line u is \(\frac{8}{5}\).
