Answer:

(3, 0)

Step-by-step explanation:

we have

7x+3y=21

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

7x+3(0)=21

7x=21

Divide by 7 both sides

x=3

therefore

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

Is the point (-1,5) a solution to the equation y=2x-4?
lyudmila [28]
No because if you plug in -1 for x and 5 for y 5 doesn’t equal -6. You just plug in the point as x and y and if the equation is true then the point is a solution.
