Answer:x=1

Step-by-step explanation:

y=y

y = -x + 10

y = 7x + 2

-x+10=7x+2

10=8x+2

8=8x

x=1

Two separate linear functions are expressed by the graph and by the equation. Select all that apply.
Andre45 [30]

Answer:

First option: The slope is negative for both functions.

Fourth option: The graph and the equation expressed are equivalent functions.

Step-by-step explanation:

<h3> The missing graph is attached.</h3><h3> </h3>

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Given the equation:

y=-4x-4

We can identify that:

m=-4\\b=-4

Notice that the slope is negative.

 We can observe in the graph that y-intercept of the other linear function is:

b=-4

Then, we can substitute this y-intercept and the coordinates of a point on that line, into y=mx+b and solve for "m".

Choosing the point (-2,4), we get:

4=m(-2)-4\\\\4+4=-2m\\\\m=-4

Notice that the slope is negative.

Therefore, since the lines have the same slope and the same y-intercept, we can conclude that they are equivalent.

The city designers drawing the road map for new housing development hurricane Ln runs through the coordinates (11, 5) and (-1, 1
AnnyKZ [126]

Answer:

-3

Step-by-step explanation:

Use slope formula to find the slope of the first road:

(y2 - y1) / (x2 - x1)

(1 - 5) / (-1 - 11)

-4 / -12

1 / 3

The slope of a line perpendicular to this line would just be the negative reciprocal of the slope:

-3 / 1 or just -3

tatyana61 [14]

0.998  is  9.222 away from  10.22 ,
but it's only 2.098 away from  -1.10 .

So  -1.10  is quite a bit closer.
