Answer:
The x-intercept is -7/5.
Explanation:
Firstly, you must know what is intercept. Intercept is the line where it touches the axis. When a line touches the one axis, the other axis must be zero. So in this question, it given to us to find the x-intercept which means that y coordinate is zero. We have to let y equals to zero and solve for the value of x :
Let y = 0,
5x - y = -7
5x - 0 = -7
5x = -7
x = -7/5(improper fraction) or -1 2/5(mixed no.)
