<u>Given</u>:
Let time be the independent variable.
Let mile marker be the dependent variable.
On one highway, Gabriela noticed that they passed mile marker 123 at 1:00. She then saw that they reached mile marker 277 at 3:00 and Mr. Morales was driving at a constant speed.
The coordinates of the points on this line are (1,123) and (3,277)
We need to determine the slope of the line.
<u>Slope of the line:</u>
The slope of the line can be determined using the formula,
Substituting the points (1,123) and (3,277) in the above formula, we get;
Therefore, the value of the slope of this line is 154.
<span>I would estimate it was approximately 600 miles altogether. Since 317 is slightly more than 300 miles, we can round it down and use 300 as an approximation for that number. Since 289 is slightly less than 300, we can round that one up to 300 as an estimate. When you add 300 and 300, you get 600. This can be used as a ballpark figure for the the answer of 317 + 289 miles because we used a close benchmark for each number and added those together.</span>
Answer:
x = -8
Step-by-step explanation:
-7(x + 6) = 14
-7x + -42 = 14
-7x = -56
x = 8
