What is the gradient of the straight line 2y = -3x - 8 ?

lions [1.4K]

Answer:

- $\frac{3}{2}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope (gradient) and c the y- intercept )

Given

2y = - 3x - 8 ( divide all terms by 2 )

y = - $\frac{3}{2}$ x - 4 ← in slope- intercept form

with gradient = - $\frac{3}{2}$
