Is (-4,2) a solution of 4x+5y <= -7 ? Choose 1 answer: (A) Yes (B) No

Substitute point into inequality: Substitute the point (-4, 2) into the inequality 4x + 5y ≤ -7. Calculate 4(-4) + 5(2) to see if it is less than or equal to -7. 4(-4) + 5(2) = -16 + 10 = -6 Check if -6 ≤ -7.Calculate value: Determine if the calculated value satisfies the inequality. Since -6 is not less than or equal to -7, the point (-4, 2) does not satisfy the inequality 4x + 5y ≤ -7.

(A) Yes

\newline

(B) No

Substitute point into inequality: Substitute the point $(-4, 2)$ into the inequality $4x + 5y \leq -7$ . $\newline$ Calculate $4(-4) + 5(2)$ to see if it is less than or equal to $-7$ . $\newline$ $4(-4) + 5(2) = -16 + 10 = -6$ $\newline$ Check if $-6 \leq -7$ .
Calculate value: Determine if the calculated value satisfies the inequality. $\newline$ Since $-6$ is not less than or equal to $-7$ , the point $(-4, 2)$ does not satisfy the inequality $4x + 5y \leq -7$ .
