finding the distance from (–6, 2) to the origin. Use (0, 0) as (x1, y1). d = StartRoot (x 2 minus x 1) squared + (y 2 minus y 1)
Naddik [55]

Answer:

2√10

Step-by-step explanation:

Given the coordinates (-6, 2) and (0,0)

We are to find the distance between the coordinates. Using the distance formula;

d = √(x2-x1)²+(y2-y1)²

d = √(0-2)²+(0+6)²

d = √(-2)²+(6)²

d = √4+36

d = √40

d = √4*10

d = 2√10

Hence the required distance is 2√10

Vertical angles are congruent.
10x+60=30x-20
20x=80
x=4

All four angles add up to 360 degrees.
360-100-100=360-200=160
160/2=80

100, 100, 80, 80

What is the slope of the line in the graph shown above?
erastova [34]
Use the 2 points and use the formula
\frac{y2 - y1}{x2 - x1}
to get slope
\frac{3 - 1}{0 - 1}
and you get a slope of -2
for the second question its non of the above? i think the x intercept is 0.6666. if you're talking about y intercept then its -5
