x-intercept
...i need the answer to that too...
The graph of y = x - 8 is a straight line. The slope of the line is 1, and it intersects the y-axis at the point y = -8.
Count the number of many times the graph intersects the x-axis. Each crossing point is a root of the equation.
At what point does line represented by the equation 8x + 4y = -4 intersects the y-axis, and at what point in the negative direction of x-axis.
