Answer:

The correct answer is 1/49

Step-by-step explanation:

In order to find this, we first can eliminate the negative in the exponent by putting the whole this in the denominator.

(-7)^-2 = 1/(-7)^2

Now we can evaluate the denominator

1/(-7)^2 = 1/49

Through: (2,2), parallel to y=x+4
lana66690 [7]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have to, if two lines are parallel then their slopes are equal.

Given the line y = x + 4, with slopem_ {1} = 1. A parallel line will have slope m_ {2} = 1and its equation will be of the form:

y = x + b

We substitute the given point and find "b":

2 = 2 + b\\2-2 = b\\b = 0

Finally, the equation is:

y = x

Answer:

y = x

Vhat is the equation of the line that is parallel to the
ozzi

Step-by-step explanation:

second one because

only x+2y=8 passes through the point (2,3)

the proof is 2+2*3=2+6=8

if we replace the given point to the other equations we will take wrong results for example

first equation

x+2y=4. 2+2*3=2+6=8 that is not equal to 4
