Question

Line t passes through points (1, 11) and (5, 2). Line u is parallel to line t. What is the slope of line u?

Answer 1

Answer:

slope = - $\frac{9}{4}$

Step-by-step explanation:

Calculate the slope of line t using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (1, 11 ) and (x₂, y₂ ) = (5, 2 )

m = $\frac{2-11}{5-1}$ = $\frac{-9}{4}$ = - $\frac{9}{4}$

Parallel lines have equal slopes , then

slope of line u is - $\frac{9}{4}$
