PLZ ANSWER QUESTION IN PICTURE

Sophie [7]

Answer: $y=\frac{1}{3}x+\frac{13}{3}$

Step-by-step explanation:

(slope = m)

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{4-6}{-1-5}=\frac{-2}{-6}=\frac{1}{3}$

$y=mx+b, (5,6), (-1,4), m=\frac{1}{3}$

$y=mx+b\\6=\frac{1}{3}(5)+b\\b=6-\frac{5}{3} \\b=\frac{13}{3}\\y=\frac{1}{3}x+\frac{13}{3}$

Quick!!

3241004551 [841]

Answer:

(x - 3) inches

Step-by-step explanation:

the ratio of -15 (of the area term) and +5 (of the length term) suggests a term for the width ending in -3. and we need an x in there to get x² for the area.

so, immediate assumption is (x-3) for the width.

let's check

(x+5)(x-3) = x² + 5x - 3x - 15 = x² + 2x - 15

correct.
