Answer:
The equation of the line is:
Hence, option C is correct.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
- m is the slope
- b is the y-intercept
Given the table
Gallons Miles Driven
8 224
10 280
4 112
Finding the slope between any two points, let say (8, 224) and (10, 280)
now substituting (8, 224) and m = 28 in the slope-intercept form of line equation
224 = 28(8) + b
224 = 224 + b
b = 0
Thus, the y-intercept b = 0
now substituting b = 0 and m = 28 in the slope-intercept form of line equation
Therefore, the equation of the line is:
Hence, option C is correct.
