What is the slope of the line whose equation is -2y = -3x + 5?

barxatty [35]

Answer:

$m = \frac{3}{2}$

Step-by-step explanation:

Use the slope-intercept form y = mx + b to find the slope m.

In this way, we can conclude that we can write it in slope-intercept form, y = mx + b:

$y = \frac{3}{2} x - \frac{5}{2}$

Your correct answer would be:

$y = \frac{3}{2} x - \frac{5}{2}$

Have a marvelous day.
