What is the slope of the line represented by the equation 3x + 4y
12?

Are you looking for coordinates or a equation?

Step-by-step explanation:

y=-3/4x+3

Step-by-step explanation:

3x+4y=12

-3. -3

4y=-3x+12 (I put the 3x first just so that it is already in slope intercept form)

4y/4=-3x/4+12/4

y=-3/4x+3

a

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
