Can someone lmk what this is plz

y+9= -10(x-1)

Use the slope formula: m=y2-y1/x2-x1
m=101-(-9)/-10-(1)
Simplify and you get m=-10

Now use the point slope formula
y-y1=m(x-x1)

y-(-9)=(-10)(x-(1))
Simply the equation & keep it in point slope form
y+9=-10(x-1)
Solve for you and simply. Move all term not containing y to the right side of the equation. And you should get y+9= -10(x-1)
