State the slope and y-intercept for the equation below:
3y -5x = 9
You can use the picture shown on the right as reference.
Looking at the equation of a line below:
We know that the equation is not in the Slope-Intercept Form. Hence, we have to change this equation into the form of y=mx+b.
To change the equation into the form of y=mx+b, we need to make y as the subject of the equation (i.e. y = something). Therefore:
Now, from the equation:
When we compare it with y = mx+b, we have:
slope = m = 5/3
y-intercept = b = +3 = 3
Clearly, the answer is A.
