Answer:
see below
Step-by-step explanation:
Let C be at (0,0)
D is at (7,12)
The slope is
m = (y2-y1)/(x2-x1)
= (12-0)/(7-0)
= 12/7
The equation of the line is y = mx+b where m is the slope and b is the y intercept
y = 12/7x +b
The y intercept is (0,0)
y = 12/7x +0
y = 12/7x
The domain is the input values or the values that x can take
X goes from 0 to 7
Domain: {0≤x≤7}
The range is the output values or the values that y can take
y goes from 0 to 12
Range: {0≤y≤12}
