Write an equation, in slope-intercept form, of a line that has a slope of -2 and passes through the point (-9, -5).
The equation written in slope-intercept form is?
The equation written in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
Given that the slope is -2, we can substitute -2 for m in the equation.
Now we need to find the value of b. We can use the given point (-9, -5) to solve for b.
Plugging in x = -9 and y = -5 into the equation, we get -5 = -2(-9) + b.
Solving for b, we get -5 = 18 + b.
Subtracting 18 from both sides, we get b = -23.
Now we can substitute -2 for m and -23 for b in the slope-intercept form equation.
The equation is y = -2x - 23.
