Answer:
y + 3 = -6(x + 9) or y = -6x - 57
Step-by-step explanation:
We can use the point-slope form for this situation.
Point-slope form: y - y₁ = m(x - x₁), where m = slope and (x₁, y₁) are given coordinates.
Plug in: y + 3 = -6(x + 9)
This can be changed to the more common slope-intercept form.
Multiply: y + 3 = -6x - 54
Subtract: y = -6x -57
Answer:
y=-6x-57 (this answer is in slope-intercept form)
I don't know what your choices are and if you can select multiple answers or not.
Step-by-step explanation:
y=mx+b is an equation for a line with slope m and y-intercept b.
We are given m=-6 so we will plug this in giving us: y=-6x+b.
Now we need to find b, the y-intercept. Let's use a point (x,y) we know is on the line of y=-6x+b to find b.
We know (x,y)=(-9,-3) is on that line. So our line should satisfy this point. We must pick a b so that happens. Plug (x,y)=(-9,-3) into the equation now.
-3=-6(-9)+b
-3=54+b
-3-54=b
-57=b
So the equation is y=-6x-57
