Question

Find the slope of the line $2y+5x=7$.

• A. $\frac{-5}{2}$
• B. $\frac{5}{2}$
• C. 5
• D. -5

Answer 1

The correct option is A

$\frac{-5}{2}$

The equation of the line is $2y+5x=7$

Writing this equation with 'y' as the subject we get,

$2y=-5x+7$

y = $\frac{-5}{2}x$ + $\frac{7}{2}$

Comparing with slope - intercept form $y=mx+c$ we get

$slope\left(m\right)=\frac{-5}{2}$
