Arionna needed to graph triangle PQR reflected across the y-axis. Her work is shown below.

Which statements identify her errors? Check all that apply.
Arionna did not find the correct point for P’. She should have negated the x-value, not the y-value.
Arionna did not find the correct value for Q’. All points in a reflection will move.
Arionna did not find the correct value for R’. She should have negated the y-value, not the x-value.
Arionna’s red triangle should be reflected below the horizontal axis rather than across the vertical axis.
Arionna switched the order of the coordinates of P’ (3, –7) when she graphed them.

Arionna’s Work:

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

i belive that is the answer

answer: 60%

explanation:
