Answer:
(0,0) and (7,10)
Step-by-step explanation:
recall that the slope - intercept form of a linear equation can be given as
y = mx + b
where m = slope and b = y intercept
in our case, we are given that slope, m = 10/7, hence our equation becomes
y = (10/7) x + b
since we are not given any information about the y-intercept, we can simply pick a value for b that is most convenient for us.
We pick b = 0, hence the equation simplifies to:
y = (10/7) x ----- eq 1
we can see immediately that if x = 0, y must also = 0
proof if x = 0:
y = (10/7)(0) =0
since 0 is an integer, then (0,0) must be the first point.
we can also observe that for y to be an integer, we must get rid of the denominator 7. We can do this by multiply the right side by 7. Hence we let x = 7:
y = (10/7) x 7
y = 10
hence (7,10) is the second point.
Answer:
hotogs=$1.50 hamburgers=$1
Step-by-step explanation:
h=hotdog b=hamburger
7h+4b=13
4h+7b=14.5
(7h+4b=13)-4b
4h+7b=14.5
h=-0.57b+1.86
4h+7b=14.5
Divide total miles by miles per gallon:
364 miles / 20 miles per gallon = 18.2 gallons
