Hint: First, divide 15/100 by -7 1/2 to find the speed, then use -70 to divide the speed to get an answer!!
None. Because when you solve for x, x is eliminated.
Given:
The equation of line is

To find:
The x-intercept and y-intercept.
Solution:
The equation of line is

Putting x=0, we get


So, the y-intercept is (0,3).
Putting y=0 in the given equation, we get


So, the y-intercept is (-3,0).
Therefore, the coordinates of the point where the line intersects the y-axis are (0,3). The coordinates of the point where the line intersects the x-axis are (-3,0).
You have to substitute each of the numbers given.
