  our X is 30 because 3x = 90 and if we divide that by 3 then we are left with 30, I knew it was equal to 90 degrees because of the little red box that symbolizes a 90 degree angle.

  So now that we know X = 30 we can plug it in for (2x + 3y)

2(30) + 3y is equal to (60 + 3y) and if we equal that to the other side 3x and plug in for x on that side, we have a new equation of 90 = 60 + 3y so then from here we subtract 60 from both sides and are left with 30 = 3y and finally we divide 3

and our final answer is Y = 10 (((((((((((((((((((((((((((((:

What equation is represented by the equation on the graph ?
solmaris [256]

Answer: The correct option is D.

Explanation:

From the graph we noticed that the x intercept of the line is (2,0) and the y-intercept is (0,2).

If the line passing through two points then the equation of line is,

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

Since the ien passing through (2,0) and (0,2).

y-0=\frac{2-0}{0-2}(x-2)

y=-1(x-2)

y=-x+2

This equation is represented by option D, therefore the option D is correct.
