The y-intercept happens when x = 0, so if y = 2x - 5, then the y-intercept happens when y = 0 - 5, or -5.

As written this is not a graphable thing. I does not represent a graphable equation because there is no "=" sign. Whatever the equation might be, the x intercept is found by setting y=0, which leaves you with an equation for x, which is the intercept.
Slope: -2 Intercept: 5
Not sure exactly what the equation is; answers.com eliminates some symbols.However, if you have a line of the form: y = mx + b Then "m" is the slope (and "b" is the y-intercept). For example, in the equation: y = -5x + 3 -5 is the slope, and +3 is the y-intercept.
Call the intercept with the y-axis b. The equation for the line is then y=5x+b With the information about the x-intercept we get: 0=5*7+b b=-35
y = 5x - 3
