Answer:
y = - x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 1, thus
y = - x + c ← is the partial equation
To find c substitute (2, 0) into the partial equation
0 = - 2 + c ⇒ c = 0 + 2 = 2
y = - x + 2 ← equation of line
Answer: A
<u>Step-by-step explanation:</u>
x² + Mx + 18
∧
1 + 18 = 19 or -1 + -18 = -19
2 + 9 = 11 or -2 + -9 = -11
3 + 6 = 9 or -3 + -6 = -9
M can be +/- {19, 11, or 9}.
