Answer:
Step-by-step explanation:
We can form an equation from the two given points.
The standard form of an equation for a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).
We can calculate the slope from the two given points, (10,0) and (0,-15). Slope is Rise/Run, where Rise is the change in y and Run is the change in x.
From the two given points, starting at (0,-15) and ending at (10,0):
Rise = (0-(-15)) = +15
Run = (10-0) = 10
Rise/Run (slope) = 15/10 or 1.5
The equation becomes y = (1.5)x + b
We know b, since it is the value of y when x=0. The point (0,-15) says -15 when x=0. You can also can find b by entering either of the two given points and solving for b. I'll pick (10,0):
y = (1.5)x + b
(0) = (1.5)*(10) + b
0 = 15 + b
b = -15
The equation is y = (1.5)x - 15
