Answer

Therefore, the slope of this line is $\frac{5}{2}$ and the y-intercept is $-5$.

Work Step by Step

To find the slope and y-intercept of this equation, we want to rewrite it in the slope-intercept form. First, we subtract $5x$ from each side to isolate $y$ to one side of the equation: $$-2y = -5x + 10$$ Divide by $-2$ to solve for $y$: $$y = \frac{-5}{-2}x -5$$ Simplify: $$y = \frac{5}{2}x -5$$ The equation has been rewritten in slope-intercept form, which is given as: $$y = mx + b$$ where $m$ is the slope and $b$ is the y-intercept. Therefore, the slope of this line is $\frac{5}{2}$ and the y-intercept is $-5$.
