Remember, the y-intercept is where the x-value is equal to zero. The easiest way to do this is to solve an equation in terms of x, for y.
-7y + x - 1 = 5x + 15
-7y = 5x - x + 15 + 1
-7y = 4x + 16
y = (-4/7)x - 16/7
Now that you have solved an equation for y, simply substitute 0 in for x to find the y-intercept.
y = (-4/7)(0) - 16/7
y = 0 - 16/7
y = -16/7
This is the y-coordinate of where your y-intercept will occur. Since it is a y-intercept, the x-value is 0, giving you the ordered pair ( 0 , -16/7 ).
It equals 285
find x+x+x when x=15 15+15+15=45
45
The x-intercept is (15 0)
Without the inclusion of an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be a straight line equation

We cannot find out the y and x intercept for the equation 3x plus 5y equals -15 by a single equation . But , we can try a hit and trial method for the same . when x =0 y =-3. when y=0 x=-5.
-9
15 plus -3 equals 12 12 divided by -6 equals -2
8 plus 15 = 23
-15 plus 20 is 5.
No. It equals 15.
