Explanation:
The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.
Given the slope m = -2 and the y-intercept (a, b) = (-5, -4), we can substitute these values into the equation to get:
y = mx + b
y = -2x + (-4)
y = -2x - 4
Therefore, the equation in slope-intercept form is y = -2x - 4.
