Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
y=x-2
We know that Reflecting over the x-axis inverts the sign of the y-coordinate.
Thus, after reflecting over the x-axis, the equation would be:
-y = x - 2
Now, writing the equation in the slope-intercept form
y=mx+b
where
so the equation in the slope-intercept form
-y = x - 2
y = -x + 2
Here,
Answer:
In short, the distance formula is a formalization of the Pythagorean Theorem using x and y coordinates. In other words, they are the same thing in two seemingly different contexts. The distance formula makes sense in a coordinate context. It's used to compute the distance between two points in an orthogonal coordinate system (i.e. a plane with a coordinate system such that). In short, If you plot 2 points on a graph right, you can form a triangle between the 2 points. You can determine the legs's sizes using the coordinates of the points. Pythagorean theorem is then used to find the hypotenuse, which IS the distance from one point to the other.

Answer: y=4
Step-by-step explanation:
7-y-y=-1
Combine like terms
7-2y=-1
Subtract seven on both sides of the equation
7-7-2y=-1-7
-2y=-8
Divide both sides by -2
-2y/-2=-8/-2
y=4
Check the answer by plugging 4 back in the equation for y.
7-4-4=3-4=-1
The final answer is y=4
Answer:
m = - , c = -
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + 3y + 4 = 0 ( subtract 2x + 4 from both sides )
3y = - 2x - 4 ( divide all terms by 3 )
y = - x - ← in slope- intercept form
with slope m = - and y- intercept c = -
