Answer: D. y = 2x + 11
Step-by-step explanation:
The slope-intercept form is:
where m is the slope of the line and b is the y-intercept.
To find the slope:
Then, the slope-intercept form so far is:
Now, to find the y-intercept, you're going to choose one of the two points given and substitute it into the equation (the first coordinate into the x, and the second coordinate into the y), and then isolate the b. In this case, let's use the first point (3, 17):
Substituting, you're left with the final slope-intercept form equation of the line passing through (3, 17) and (7, 25):
Answer:
755,160 ways
Explanation:
We're told that 31 cars are in a race.
Considering the order in which the cars can finish in the top 4 positions, any of the 31 cars can finish in the first position, any of the remaining 30 cars can finish in the second position, any of the remaining 29 cars can finish in the third position and any of the remaining 28 cars can finish in the fourth position, so the different numbers of ways can be determined as seen below;
