Plugging in the numbers 7x - 2y = 39 fitted and made sense
Don't hold me accountable but I believe it is the 2nd equation.
The correct answer is D, y = 7x + 5
Calculate the slope by doing y2 - y1 / x2 - x1
y2 - y1 / x2 - x1
61 -33 / 8 - 4
28 / 4
7
Next find the y intercept by looking at the graph, which is 5 in the case
Put it together and you have y = 7x + 5, or option D
The answer to this question is A
