Answer:
The slope would be C) -1/2
Step-by-step explanation:
To find it, we need to use the slope formula and two points on the line. The points we'll use are (0, -3) and (2, -4)
m(slope) = (y2 - y1)/(x2 - x1)
m = (-3 - -4)/(0 - 2)
m = 1/-2
m = -1/2
elimination means to get rid of one variable by altering the coefficients of variable (by multiplying and diving by some constant number)
in this case, if you just add the two equation, y gets cancelled you get 5x=20 or x=4
put it in any equation to get y (this works because both lines pass through the same point, so they must satisfy that point) to get y=2
The graph is a horizontal line at 70 units above the x-axis and parallel to it. f(x) doesn't depend on the value of 'x'. It's always 70.

34 miles/gallon is our initial expression
to convert that to kilometers / liter we just need to express given equalities of miles to kilometers and galons to liters.
34 * 1.61/3.79 = 14,443 km/liter
Answer is 14,443 km/liter
