First find the slope of the line connecting these two points:

6-5

m = ------------ = -1/2

-4+2

Substitute this slope into y = mx + b: y = (-1/2)x + b.

Next, subst. 5 for y and -2 for x, and find b:

5 = (-1/2)(-2) + b, or 5-1=b. Then b = 4, and

the equation of the line is y = (-1/2)x + 4.

First you find the slope of the equation using the formula
M= y2-y1/x2-x1
M= 5-6/-2-(-4)
M= -1/2
Using slope intercept form which is y=mx+b, you write y=-1/2x+b
Now in order to find b you simple substitute one of the given points
I choose (-4,6)
6=-1/2(-4)+b
6=2+b
b=4
So final answer would be y=-1/2x+4

If five slices of pizza costs 5.50 how much would two slices cost? ten slices? half a slice?
tensa zangetsu [6.8K]

Answer:

The first thing we must do for this case is to define variables.

We have then:

x: number of slices

y: total cost

We write the linear function that relates the variables.

We have then:

Then, we evaluate the number of slices to find the total cost.

-two slices cost:

We substitute x = 2 in the given equation:

Answer:

two slices = 2.2 $

-ten slices cost:

We substitute x = 10 in the given equation:

Answer:

ten slices = 11 $

-half a slice cost:

We substitute x = 1/2 in the given equation:

Answer:

half a slice = 0.55 $

What is the equation of the following graph in vertex form?
VARVARA [1.3K]

Answer:

Hello,

answer B

Step-by-step explanation:

Vertex is (-3,-1)

The equation of the parabola should be:

y=k*(x+3)²-1

(0,8) is a point of the parabola:

8=k*(0+3)²-1

8+1=9k

k=1

Equation is y=(x+3)²-1

A flagpole broke in a storm. 7 meters are still sticking straight out of the ground, where it snapped, but the remaining piece h
serious [3.7K]
32 meters tall.
It would form a right triangle, in which the shorter leg is 7m and the longer leg is 24m.  You're looking for the last side, the hypotenuse.  So use the Pythagorean theorem. a^2 + b^2 = c^2 , in which a and b are the legs and c is the hypotenuse.
Therefore, you get 7^2 + 24^2 = c^2.
Which is, 49 + 576 = c^2
Add, 625 = c^2.
Take the square root of 625, which is 25.   So, the length of the hypotenuse (last side) is 25m.  Add the 7m that is sticking out of the ground, to get 32m.

Answer:

∠F = 42°

Step-by-step explanation:

similar triangles have congruent corresponding angle measures.

so if ΔABC ~ ΔEFG, then ∠B corresponds with ∠F, so ∠F = ∠B

∠F = 42°
