You didn't give a graph but I will visualize what it looks like for you.
The line is going through (0,-2) because that is the y-intercept.
The line has a slope of 3.
So, the line goes through:
(1,1)
(2,4)
(3,7)
(4,10)
(5,13)
5 inches by 7 inches.
To find the area of a parallelogram, you can just do base * height. In this case, all other options, once multiplied, equal 36 square inches, it's only 5 * 7 that equals 35 square inches.
-3x + 7 = -1
-3x = -8
x = 8/3
In order to solve for x, you must isolate the variable. Because -1 and 7 are like terms, use inverse operations to subtract 7 from both sides. Then, divide both sides by -3. This should get you x = 8/3, which can’t be reduced any more (unless you convert to decimal, which is about 2.666666…) Feel free to comment any questions you have! Always happy to help :)
