What is an equation of the line that passes through the points (0, -4) and (-4, 6)?
1 answer:
I got this answer by first using the slope formula, which would result into for which the answer would be - ⅔ Then, the y-intercept could be found easily, since you already have it., which is (0,4). Since the format for all linear equations are y=mx+b , in which b means the y-intercept and m means the slope. So then, if you substitute - ⅔ for m and 4 for b , you would get

Answer:
300 miles
Step-by-step explanation:
Let
x ----> the number of miles
y ----> the total cost for rent a car
we know that
The equation of the line in slope intercept form is equal to
where
m is the slope or unit rate
b is the y-intercept or initial value
<u><em>Prestige car rentals</em></u>
we have that
The slope is equal to
The y-intercept is
therefore
-----> equation A
<u><em>Gateway auto</em></u>
we have that
The slope is equal to
The y-intercept is
therefore
-----> equation B
For what number of miles both companies charge the same price>
Equate equation A and equation B
solve for x
