Given the function :
To find which line represents the given function , find x- intercept and y - intercept
So, the y- intercept of the function is the value of y when x = 0
So, when x = 0
y = 0 - 7 = -7
The x - intercept is the value of x when y = 0
So, when y = 0
0 = x - 7
x = 7
So, the function passes through the points ( 0 , -7 ) and ( 7 , 0 )
Now, look to figure to find which line is the correct line
So, it will be the line D, because he is the only line is passing through one of the points.
The answer is : D
