Y = mx + b
slope(m) = -1/2
(5,2)...x = 5 and y = 2
sub and find b
2 = -1/2(5) + b
2 = -5/2 + b
2 + 5/2 = b
4/2 + 5/2 = b
9/2 = b
so ur equation for this line is : y = -1/2x + 9/2
y = -1/2x + 9/2......(7,r)....when x = 7
y = -1/2(7) + 9/2
y = -7/2 + 9/2
y = 2/2
y = 1
so ur missing variable is 1......ur set of points would then be (7,1) <=

Answer:
x = 1/3, x = -1.
Step-by-step explanation:
2x(x + 2) + (x - 1)² = 2
Distribute the 2x into x + 2.
2x² + 4x + (x - 1)² = 2
Square (x - 1).
2x² + 4x + x² - x - x + 1 = 2
Combine terms.
2x² + x² + 4x - 2x + 1 = 2
Combine terms again.
3x² + 2x + 1 = 2
Subtract 2 from both sides.
3x² + 2x - 1 = 0
Factor.
(3x - 1)(x + 1) = 0.
Finding the x-values here is the same thing as finding the 0s, so set both of the expressions to 0.
3x - 1 = 0
Add 1 to both sides.
3x = 1
Divide by 3.
x = 1/3.
x + 1 = 0
Subtract 1 from both sides.
x = -1.
