PLEASE HELP I NEED HELP ALSO I WILL MARK BRAINLIEST

Answer 1

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}
