standar form is y = mx + b where m is slope and b y intercept
x + 2y = -10
2y = -x-10
y = -x/2 -5
slope = m = -1/2
To solve this, present the equation in the standard slope/intercept form of y = mx + c. 'm' is the slope. 2x + 5y = 10 5y = -2x + 10 y = -2/5x + 2 Therefore, -2/5 is the slope.

It is an equation and the value of x works out as 88
There are 2 unknowns
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
