From the slope of the line, we see that 43 is a very steep slope, so the line is a near vertical line.
Also, from the point-slope form of the graph, we know that the line passes through (5,5) .
Note: (y-y1)=m(x-x1) passes through (x1,y1).
So the result is the line shown in the attached diagram, with no surprises.

Solution:

The given equation of line is :

→  y- 5 = 43 (x -5)

= y -5 = 43 x - 43 × 5 → [Using distributive property]

= y- 5 = 43 x - 215

→ 43 x - y - 215 +5 =0

→ 43 x - y -210 =0

→ y = 43 x - 210

As the slope of line→y = m x + c is ,43.

Or , tan A = 43, where A is the angle made by line in positive direction of X axis.

And Y intercept = -210

  • Vertex Form: y = a(x - h)^2 + k, with (h,k) as the vertex.

So firstly, plug the vertex into the vertex form: y=a(x-1)^2-9

Next, we first need to solve for a. Plug (0,-6) into the equation to solve for a as such:

-6=a(0-1)^2-9\\-6=a(-1)^2-9\\-6=a-9\\3=a

<u>Now we know that our equation is y = 3(x - 1)^2 - 9.</u>

Now to solve for the zeros (x-intercepts). Set y to 0 and add 9 to both sides of the equation: 9=3(x-1)^2

Next, divide both sides by 3: 3=(x-1)^2

Next, square root both sides: \pm\sqrt{3}=x-1

Next, add 1 to both sides: 1\pm\sqrt{3}=x\\2.73,-0.73=x

<u>Your x-intercepts are (-0.73,0) and (2.73,0), or B.</u>

Answer:

Positive 8

Step-by-step explanation:

The end value of -(-8) would be positive eight because when you multiply a negative by a negative, you get a positive value.

This question is essentially -1 times -8, which would equal 8

(The answer would be: 8)

I hope this helps!
