Mathematics
1 answer:
zysi [14]2 years ago
4 0

Answer:

Yes

Step-by-step explanation:

In the first equation, sub in (-3x/2) for y:

3x+4y=12

3x+4(-3x/2)=12

3x-(12x/2)=12

3x-6x=12

-3x=12

x=-4

y=-3x/2

y=-3(-4)/2

y=12/2

y=6

Since x=-4 and y=6, (-4,6) is a solution.

Passes through (3, 4) and (5, -4) how do I solve​
nikitadnepr [17]

Answer:

y = - 4x + 16

Step-by-step explanation:

Assuming you require the equation of the line passing through the points.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 4) and (x₂, y₂ ) = (5, - 4)

m = \frac{-4-4}{5-3} = \frac{-8}{2} = - 4, thus

y = - 4x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 4), then

4 = - 12 + c ⇒ c = 4 + 12 = 16

y = - 4x + 16 ← equation of line
