Answer:
y = 600x, the jet travels 12,000 miles in 20 hours
Step-by-step explanation:
Slope-intercept form of a linear equation:
where:
To find the slope, define two points on the line and use the slope formula to find the slope:
From inspection of the graph, the y-intercept (where the line crosses the y-axis) is at (0, 0). Therefore, the equation of the line is:
y = 600x
y is defined as the distance (in miles). Therefore, to find the number of hours it takes for the jet to travel 12,000 miles, substitute y = 12000 into the found equation and solve for x:
Therefore, it takes the jet 20 hours to travel 12,000 miles.
