What is the x-intercept of the equation 7x + 3y = 21? (0, 3) (0, 7) (3, 0) (7, 0)

(3, 0)

Step-by-step explanation:

we have

we know that

The x-intercept is the value of x when the value of y is equal to zero

so

For y=0

substitute in the equation and solve for x

Divide by 7 both sides

therefore

The x-intercept is the point (3,0)

3,0
