What is the slope of the line?<br> 3x-4y=7
Vinvika [58]

Answer:

3/4

Step-by-step explanation:

3x - 4y = 7.....subtract 3x from both sides

-4y = -3x + 7 ...now we divide both sides by -4

(-4/-4)y = (-3/-4)x + (-7/4)...simplify

y = 3/4x - 7/4

y = mx + b

y = 3/4x - 7/4.....so the number in the m position is 3/4 <== ur slope
