Answer:
Area: 6x+6
Perimiter: 4x+10
Step-by-step explanation: to find the area of something multiply the width times the height. to find the perimeter of something add each side together. use the order of operations (PEMDAS).
Area=3(2x+2)
Area=6x+6
Perimeter=3+3+(2x+2)+(2x+2)
Perimeter=6+4x+4
Perimeter=4x+10

Answer: y = (-2/5)x - 7
This is the same as writing 
======================================================
Explanation:
Any linear equation is of the form y = mx+b, known as slope-intercept form
m = slope
b = y intercept
We'll replace m with -2/5 and replace b with -7 to get y = (-2/5)x + (-7) which simplifies to y = (-2/5)x - 7
