Answer:
[tex]y =- \frac{1}{5}x - 4[/tex]
Step-by-step explanation:
Slope-intercept form: y = mx + b
y = (x , y)
m = slope
x = (x , y)
b = y-intercept
First, set the given equation in slope intercept form:
[tex]3x + 15y = -60\\\\15y + 3x (-3x) = -60 (-3x)\\\\15y = -3x - 60[/tex]
First, isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Divide 15 from both sides of the equation:
[tex]15y = -3x - 60[/tex]
[tex]\frac{(15y)}{15} = \frac{(-3x - 60)}{15}[/tex]
Simplify:
[tex]y = \frac{-3x - 60}{15} = -\frac{1}{5}x - 4[/tex]
[tex]y =- \frac{1}{5}x - 4[/tex] is your answer.
