On a bicycle, Brittany rides for 2 hours and is 20 miles from her house. After riding for 4 hours, she is 38 miles away.
What is Brittany's rate? 10
miles per hour
How far away from her house did Brittany start riding?
miles
Write an equation to model this situation (use d for distance from her house in miles and h for hours).

the answer

b. they are parallel and will never intersect.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
