write an equation in point-slope form for the line through the given point with the given slope. (10, –9); m = –2 y – 10 = –2(x 9) y – 9 = –2(x – 10) y 9 = –2(x – 10) y – 9 = –2(x 10)
y - y₁ = m(x -x₁)
slope m = -2, from point (10, -9) , x₁ = 10, y₁ = -9
y - y₁ = m(x -x₁)
y - -9 = -2(x - 10)
y + 9 = -2(x - 10)
Answer:
The required equation is \(y+9=-2(x-10)\)
Step-by-step explanation:
To find : Write an equation in point-slope form for the line through the given point with the given slope. (10, -9); m = -2
Solution :
The slope formula of the equation of line is
\((y-y_1)=m(x-x_1)\)
Where, m is the slope and \((x_1,y_1)\) is the point.
According to question,
\((x_1,y_1)=(10,-9)\)
The slope is m=-2
Substitute the value in the equation,
\((y-(-9))=(-2)(x-10)\)
\((y+9)=-2(x-10)\)
Therefore, The required equation is \(y+9=-2(x-10)\)
