Answer
Select and check your answer...
A. m = 5/3 and b = 3
B. m = 5/3 and b = -3
C. m = -5/3 and b = 3
D. m = -5/3 and b = -3

Step by Step Solution
Step 1
Looking at the equation of a line below:
3y -5x = 9
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.
Step 2
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:
Step 3
Now, from the equation:
When we compare it with y = mx+b, we have:
slope
= m = 5/3
y-intercept
= b = +3 = 3
Step 4
Clearly, the answer is A.
