Answer:
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the slope we must first write the equation in the general equation above
That's
6x + 3y = 15
Make y the subject
Send 6x to the other side of the equation
3y = - 6x + 15
Divide both sides by 3
[tex] \frac{3y}{3} = - \frac{6}{3} x + \frac{15}{3} [/tex]
We have
y = - 2x + 5
Comparing with the general equation above
Slope / m = - 2
Hope this helps you
Answer:
Slope = -2
Step-by-step explanation:
6x + 3y = 15
=> Make the "y" alone.
=> 6x - 6x + 3y = -6x + 15
=> 3y = -6x + 15
=> 3y/3 = -6/3x + 15/3
=> y = -2x + 5
We use a formula => y = mx + b
In the above formula, "m" = slope.
b = y-intercept
So, the slope = -2
