Answer:
A
Step-by-step explanation:
To determine if the ordered pairs lie on the graph, substitute the x- coordinate of the point into the equation and if the value agrees with the y- coordinate of the point then it lies on the graph
A
x = - 2 : y = -2(- 2) + 7 = 4 + 7 = 11 ≠ 3 ← (-2,3) not on graph
B
x = - 1 : y = - 2(- 1) + 7 = 2 + 7 = 9 ← (- 1, 9) lies on graph
C
x = 3 : y = -2(3) + 7 = - 6 + 7 = 1 ← (3, 1) lies on graph
D
x = 4 : y = - 2(4) + 7 = - 8 + 7 = - 1 ← (4, - 1) lies on graph
30/-6 equals 5. You’re welcome
Answer:
i think b
Step-by-step explanation:
(2,2). When x of the line is 2, y of the line must be 2.
(-2,-2). When x of the line is -2, y of the line must be -2.
(2,2). y=mx+b or 2=1 × 2+b, or solving for b: b=2-(1)(2). b=0.
(-2,-2). y=mx+b or -2=1 × -2+b, or solving for b: b=-2-(1)(-2). b=0.
The equation of the line that passes through the points
(2,2) and (-2,-2)
is
y=1x
b came out to be zero, so there is no "+b" term.
3x-2 if x is less an or greater than 1, will be a negative y value.
-2x+3 when x is greater than 1 will also be a negative y value.
The graph would be the first one ( an upside down V)
