-4
7

submit question

Explanation:

Step1: Evaluate for \( x = 1 \)

Substitute \( x = 1 \) into \( y = -5x + 2 \).
\( y = -5(1) + 2 = -5 + 2 = -3 \)

Step2: Evaluate for \( x = 3 \)

Substitute \( x = 3 \) into \( y = -5x + 2 \).
\( y = -5(3) + 2 = -15 + 2 = -13 \)

Step3: Evaluate for \( x = -4 \)

Substitute \( x = -4 \) into \( y = -5x + 2 \).
\( y = -5(-4) + 2 = 20 + 2 = 22 \)

Step4: Evaluate for \( x = 7 \)

Substitute \( x = 7 \) into \( y = -5x + 2 \).
\( y = -5(7) + 2 = -35 + 2 = -33 \)

Answer:

For \( x = 1 \), \( y = -3 \); for \( x = 3 \), \( y = -13 \); for \( x = -4 \), \( y = 22 \); for \( x = 7 \), \( y = -33 \)
