Answer:
y=-1 x=26 (26,-1)
Step-by-step explanation:
We know that Mr. Garcia drives 26 miles per gallon, this means that the slope will be (26,-1)
A) The equations are shown on the attached graph.

Answer:
√629 ≈ 25.08
Step-by-step explanation:
The distance formula is useful for this.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((-12 -13)² +(6 -8)²) = √(625 +4) = √629 ≈ 25.08
The distance between the points is about 25.08 units.
C. 5/2, 3 this is the answer
<em>If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).</em>
<em>If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).</em>
