Final answer:
The slope of the line with the equation -3x + 4y = 8 is 3/4.
Step-by-step explanation:
To find the slope of the line with the equation -3x + 4y = 8, we need to rewrite the equation in slope-intercept form, y = mx + b, where m is the slope. Let's rearrange the equation:
-3x + 4y = 8
4y = 3x + 8
y = (3/4)x + 2
From this equation, we can see that the slope of the line is 3/4. Therefore, the correct answer is a) 3/4.
