Which is the equation in the slope-intercept form of the line that contains points E & F ?
sesenic [268]

Answer:

y = 4x - 12

Step-by-step explanation:

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 = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = E(4, 4) and (x₂, y₂ ) = F(2, - 4)

m = \frac{-4-4}{2-4} = \frac{-8}{-2} = 4 , then

y = 4x + c ← is the partial equation

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

Using (4, 4), then

4 = 16 + c ⇒ c = 4 - 16 = - 12

y = 4x - 12 ← equation of line

Start with the number 5,835.87 make 3 more in the tens place
Vinil7 [7]

So the tens place for this number would be the 3 for "30." It wants 3 more in the tens place, so I think it wants you to add 3 tens to make it 60, or a grand total 5,865.87. It's worded a little funny, so if you think it's something else please tell!
