Answer:

y = 2/5x + 24/5

*View graph to see the lines*

Step-by-step explanation:

y = 2/5x - 1/2

Parrel lines have the same slope

y = mx + b

y = 2/5x + b

2 = 2/5(-7) + b

2 = -14/5 +b

5(2 = -14/5 +b)

10 = -14 + 5b

+14   +14

24 = 5b

/5    /5

24/5 = b

y = 2/5x + 24/5

Hope this helps!

So all you have to do to solve these problems is substitute the y coordinate and the x coordinate into the equation.

So question 1 would be true because when you substitute the numbers in it equals the y value.

Question 2 is (4, -7)

Question 3 is False

Question 4 is true

Question 5 is true

See if you can do the rest!

Write an equation of a parabola that opens to the left, has a vertex at the origin, and a focus at (–4, 0).
8_murik_8 [283]

Answer:

y^{2}=-16x

Step-by-step explanation:

we know that

The standard equation of a horizontal parabola is equal to  

(y-k)^{2}=4p(x-h)

where

(h,k) is the vertex

(h+p,k) is the focus

In this problem we have

(h,k)=(0,0) ----> vertex at origin

(h+p,k)=(-4,0)

so

h+p=-4

p=-4

substitute the values

(y-0)^{2}=4(-4)(x-0)

y^{2}=-16x
