Question

Line p passes through points (8, 7) and (4, 4). Line q is parallel to line p. What is the slope of line q?

Answer 1

slope of line q =
`(3)/(4)`

Explanation:

calculate the slope of line p using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (8, 7 ) and (x₂, y₂ ) = (4, 4 )

m =
`(4-7)/(4-8)` =
`(-3)/(-4)` =
`(3)/(4)`

• Parallel lines have equal slopes

then slope of line q =
`(3)/(4)`
