See a solution process below:

The equation in the problem is in slope intercept form. The slope-intercept form of a linear equation is: $y = color(red)(m)x + color(blue)(b)$

Where $color(red)(m)$ is the slope and $color(blue)(b)$ is the y-intercept value.

Therefore, for this equation: $y = color(red)(-2)x - color(blue)(7)$

The Slope is: $color(red)(m = -2)$

The Y=Intercept is: $color(blue)(b = -7)$ or $(0, color(blue)(-7))$
