The equation of a line is given as 3 x – 5y = 7. Find its gradient (slope)
- \(\frac{5}{3}\).
-
\(\frac{3}{5}\).
- \(\frac{-3}{5}\).
- \(\frac{-5}{3}\).
The correct answer is: B
Explanation
the form y=mx+c
where m is the gradient and c is the y-intercept.
the equation to gives 5y=3x - 7.
divide both side by 5 the coefficient of y → \(\frac{3}{5}\)x - \(\frac{7}{5}\)
comparing this with the general equation y=mx+c,
you can see that m= the gradient= \(\frac{3}{5}\).
