Answer:
Step-by-step explanation:
To find the slope of the equation use .
So, =
. Now we can use our slope and any of the two points to write in point-slope form, which is
. Using the point (7,-6), the formula will give
.
To check, you can plug in this equation and the points into a calculator to graph. The line passes through both points.
Answer:
Proportion states that the two fractions or ratios are equal
As per the statement: Mrs. Hwang is taking her vehicle to the shop to have the gas tank expanded by 10 gallons. Now, it costs her $42.56 to fill the tank. Once the new tank is in, it will cost her $72.96
Let the tank size now be x
Since, the gas tank expanded by 10 gallons = x + 10
by definition of proportion ;
by cross multiply we get;
using distributive property;
Subtract 42.56x from both sides we get;
Divide both sides by 30.4 we get;
x = 14
Therefore, the tank is her now is, 14 gallons
