Find the line that is perpendicular to line n that passes
through point (2,-3).
if the slope of the perpendicular line is -2/5, what is the
y-intercept of the perpendicular line?

o b = -19/5
o 6=-11/5
o b=4/5
o b=2
!

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

126 maybe. sorry
