Find the slope of the line with equation 3x + 2y = 10

Guide / Hint

Hint 1: Convert the linear equation into slope-intercept form .

Hint 2: Subtract from both sides, then divide by 2.

Hint 3: Read the coefficient of which represents the slope.

Solution

Step 1 (Slope-Intercept Form): The standard slope-intercept form of a linear equation is , where is the slope.

Step 2 (Convert the given equation): We rewrite to isolate :

Dividing both sides by 2:

Step 3 (Conclusion): The slope of the line is exactly -1.5 (or -3/2).
