The equation of the line is y = -11x + 232
<h3>How to determine the equation?</h3>
The given parameters are:
Slope (m)= -11
Point (x1, y1) = (31, -109)
The linear equation is then calculated as:
y = m(x - x1) + y1
This gives
y = -11(x - 31) - 109
Evaluate the product
y = -11x + 341 - 109
Evaluate the like terms
y = -11x + 232
Hence, the equation of the line is y = -11x + 232

Student 1 and 3.

Move the negative into the brackets,
positive becomes negative while two negatives make a positive.
Answer:
Vertex: (1, -4)
intercept: (-3, 0)
Step-by-step explanation:
lets be real, you don't care about an explanation you just want the answer.
BUT... the vertex is the Y line and the Intercept is the X line
Subtract 19 from both sides
-3x=2+x
Subtract x from both sides
-4x=2
Divide both sides by -4
x=-1/2
Final answer: x=-1/2
