If you mean: y^2 + x^2 = 65 and y + x = 7 then the solutions are as follows:- When y = -1 then x = 8 When y = 8 then x = -1
-25x+y=65-25(0)+y=65y=65When finding a y-intercept you replace the value of xwith 0. The same goes for finding the x-intercept, you replace the value of y with 0 and simplify the equation.

If you mean: y^2 + x^2 = 65 and y + x = 7 then the solutions are as follows:- When y = -1 then x = 8 When y = 8 then x = -1
Given the equation y = 45x + 65, the y-intercept is 65. We know this because the equation is already in the form y = mx + b, where m is the slope, and b is the y-intercept.
subtract the x to the other side to get y=-x+65. its a straight line crossing the y-axis at 65 with a slope of -1.
65 + 65 + 65 + 65 + 65 + 65 + 65 + 65 + 65 + 65 + 65 + 65 = 65 x 12 = 780
