Slope intercept form is y = -2x + 14
Step-by-step explanation:
- Step 1: The original equation is 4x + 2y = 14.
- Step 2: Rearrange so that x is first in the right hand side of the equation.
⇒ 2y = - 4x + 14
- Step 3: Subtract 4x from both sides of the equation.
⇒ 2y = 14 - 4x
- Step 4: Divide both sides of the equation by 2 so that coefficient of y is 1.
⇒ y = - 2x + 7
This is the slope intercept form y = mx + b
Answer:
y = -3x + 8
Step-by-step explanation:
(5,-7), slope is -3
y - y₁ = m(x - x₁)
y₁ = -7
x₁ = 5
m = -3
y + 7 = -3(x - 5)
y + 7 = -3x + 15
y = -3x + 8
<span>Answer: Slope = -4.000/2.000 = -2.000
x-intercept = 2/6 = 1/3 = 0.33333
<span> y-intercept = 2/3 = 0.66667
What I'm trying to show in the graph is:
</span></span>
y tells us how far up the line goes.........
x tells us how far along...........
m is the Slope or Gradient i.e. how steep the line is.........
b is the Y-intercept i.e. where the line crosses the Y axis.......
I really hope this helps ^-^
Answer:
you are correct with -0.0081
Step-by-step explanation:
but if you are multiplying a negative times a positive it is a negative always. So you do a negative times a negative you get a positive. Then you multiply the positive with a negative to get a negative then you do the negative times a negative to get a negative.
Answer:

Step-by-step explanation:
We want to find the equation of a parabola with vertex (0,5), focus at (0,7) and directrix y=3.
This is given by 
where p=2, h=0, and k=5
We substitute these values to get:

This simplifies to:

We solve for y to get:
