Answer: y = 30x + 50
Step-by-step explanation:
let y be the distance traveled (in meters) after x minutes.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (260 - 110)/(7 - 2)
m = 150/5 = 30
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 7, y = 260 and m = 30 into y = mx + c. It becomes
260 = 30 × 7 + c = 210 + c
c = 260 - 210
c = 50
The linear model becomes
y = 30x + 50
