question and answer in the picture

Answer:
m =3/4
Step-by-step explanation:
3x-4y = 12
We need to solve for y
Subtract 3x from each side
3x-3x-4y = -3x+12
-4y = -3x+12
Divide by -4
-4y/-4 = -3x/-4 + 12/-4
y = 3/4 x -3
This is in the form y = mx+b where m is the slope and b is the y intercept
The slope is 3/4
It's a standard form: Ax + By = C
[tex]3x-4y=12[/tex]
A slop-intercept form: y = mx + b
m - slope
b - y-intercept
Convert from the standard form to the slope-intercept form:
[tex]3x-4y=12[/tex] subtract 3x from both sides
[tex]-4y=-3x+12[/tex] divide both sides by (-4)
[tex]y=\dfrac{-3}{-4}x+\dfrac{12}{-4}\\\\y=\dfrac{3}{4}x-3[/tex]
Answer:
[tex]\boxed{m=\dfrac{3}{4}}[/tex]
