Write the equation of the line parallel to y= -5 through (2,7) .

y = 7

Step-by-step explanation: The equation of the original line in standard form is y = -5. Lines with a "y = b" equation are horizontal, so we know that the parallel line will also be horizontal and follow the y=b format. The original line passes through the point (2, 7) so the equation is y = 7.

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.

ratio is 2 : 9

the answer is three

13.5 : 3
