Answer:
A
Step-by-step explanation:
Parallel lines have equal slopes
The product of the slopes of perpendicular lines = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
A
y = [tex]\frac{4}{3}[/tex] x + 2 → has slope m = [tex]\frac{4}{3}[/tex]
y = - [tex]\frac{3}{4}[/tex] x - 7 → has slope m = - [tex]\frac{3}{4}[/tex]
and [tex]\frac{4}{3}[/tex] × - [tex]\frac{3}{4}[/tex] = - 1
Thus this pair of lines are perpendicular
B are neither parallel nor perpendicular
C have equal slope and are parallel
D are neither parallel nor perpendicular
