Hii, so this was one of the questions on a previous CSAT exam (korean sat). I was curious and decided to look at a few questions
. This question I found was particularly interesting and I am close to figuring it out but i keep getting stuck. Would anyone like to explain how this works and how to solve it?

You want to be finding out what two factors (where one of them is a perfect square) has the produce of 63. It seems like 9 x 7 (9 is the perfect square) works.
The square root of 9 is 3 so we can just have
(which just means 3 times the square root of 7).
The square root of 9 is 3 so we can just have
<h2>Answer:</h2>
First, we need to find the slope of the line using <u><em>slope formula*</em></u>.
Slope of the line: <em>2</em>
Second, we determine the <em><u>y-intercept</u></em> using the slope we just found, one of the given points, and <em><u>slope-intercept form**</u></em>.
Because <em>b = 0</em>, this means that the y-intercept is the origin, (0,0), so it is not written in the equation.
Finally, we create the equation of the line.
Slope formula: <em>y₂ - y₁/x₂ - x₁</em>
Slope-intercept form: <em>y = mx + b</em>
