y = 9x/20 - 2/5
Step-by-step explanation:
Equation: 9x -20y = 8
First we rewrite the equation by making y stand alone
-20y = -9x + 8
The slope intercept form is in the form:
y = mx + c
This means the coefficient of y needs to be 1
We divide both sides of the given equation by -20 to get coefficient of y as 1:
-20y/-20 = -9x/-20 + 8/-20
Division of same sign gives positive number. Division of opposite signs give negative number.
y = 9x/20 - 8/20
In simplest form, the slope-intercept form:
y = 9x/20 - 2/5
