The middle one has an error.
Answer:
72 square feet
Step-by-step explanation:
the length is 12 and the width is 6. 12+12=24 and 6+6=12. 24+12=36
so 12x6= 72
The slope is already given in the question, so we only ned to solve for the y-intercept using y = mx + b.
4 = 3(1) + b
4 = 3 + b
4 - 3 = 3 + b - 3
1 = b
Now, write the equation in slope-intercept form.
y = 3x + 1
