The equation y = 7x -3 is not proportional
The given equation is:
y = 7x - 3
For an equation to be proportional, the y-intercept must be (0, 0)
Calculate the y-intercept of y = 7x - 3
Substitute x = 0 into the equation y = 7x - 3 to know the corresponding value of y
y = 7(0) - 3
y = -3
Therefore, the y-intercept of the equation y = 7x - 3 is (0, -3).
Since the y-intercept is not equal to (0, 0), the equation y = 7x - 3 is not proportional
