Question

whats the slope of this equation ? 3x-5y=45 Is it 3/5 -3/5 3 or 5 ?

Answer 1

solve the equation for y.
have y on the left side of the = sign.
make sure there is no number to the left of y when you are finished solving it.
once you have solved for y let me know and we can go from there.

Answer 2

3x-5y = 45
-5y = 45-3x // subtract the 3x from both sides
i have it solved, but give it a go, and post your process step by step. if you get stuck just let me know.

Answer 3

ok,
-5y = 45-3x // we found that
-y = (45/5)-(3/5)x // I divided both sides by 5
y = -9 +(3/5)x // I divided both sides by -1 and simplified
y = (3/5)x -9 // I just moved the (3/5)x and -9 around

therefore, you can find the slope since y = mx+b where m is the slope
