A car starts a journey with a full tank of gas. The equation y=16 - 0.05x relates the number of gallons of gas, y, left in the t
GenaCL600 [577]

We are given that a car starts a journey with a full tank of gas. The equation y=16-0.05x relates the number of gallons of gas (y) left in the tank to the number of miles the car has traveled(x).

A. We will find y intercept by substituting x=0 in our equation,

y=16-0.05*0

y=16

Now let us find our x-intercept by substituting y=0 in our equation,

0=16-0.05x

0.05x=16

x=\frac{16}{0.05}=320

Therefore, x-intercept is 320 and y-intercept is 16.

B. Our x-intercept represents that after travelling 320 miles there were 0 or none gallons of gas left in tank.

C. Our y-intercept represents that there were 16 gallons of gas in car tank when car started the journey.

A line intersects the points (-14,-10) and (7,5). find the slope of the line and simplify
Tpy6a [65]
The slope of any line can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)

The given points are (-14,-10) and (7,5), therefore:
y2 = 5
y1 = -10
x2 = 7
x1 = -14

Substitute with these values to get the value of the slope as follows:
slope = (5--10) / (7--14) = 5/7
