Answer 1

Answer:

$\displaystyle m_u=-\frac{7}{4}$

Step-by-step explanation:

Perpendicular Lines

If two lines t and u are perpendicular and have slopes mt and mu respectively, then the following relationship is satisfied:

$m_t\cdot m_u=-1$

Knowing line t has a slope of \frac{4}{7}, then the slope of line u can be found by solving for mu:

$\displaystyle m_u=-\frac{1}{m_t}$

$\displaystyle m_u=-\frac{1}{\frac{4}{7}}$

Operating:

$\mathbf{\displaystyle m_u=-\frac{7}{4}}$

Answer 2

Answer:

u = -7/4

Step-by-step explanation:

This is correct because to find the perpendicular, you need to find the opposite reciprocal of the slope. In this case, the slope is 4/7, so the opposite reciprocal is -7/4.
