Answer:
The absolute values of Q and R are the same
Step-by-step explanation:
The absolute value is the same as long as they have the same number whether its - or +
Answer:
-3 1/5
Step-by-step explanation:
to find the slope of the line you use the equation (y2 - 1) / (x2 - x1)
when plugged in you get
(5 + 3) / (-2 1/4 - 1/4)
then you do what is inside the parenthesis
8 / -2 1/2
8 / -2.5
lastly you divide
you get -3 1/5
that is your answer
To find the midpoint, Add the two X coordinates together then divde by two and then to the same with the Y coordinates:
X = -4 + 2 = -2 / 2 = -1
Y = 6+7 = 13/2
Midpoint = (-1,13/2)
<u>Answer:</u>
<u>Step-by-step explanation:</u>
- Given a slope and a point on the line, you can use point slope form and then rearrage your terms into slope-intercept form
- <u>SLOPE-INTERCEPT FORM</u>:
, where "m" is your slope and "b" is your y-intercept - <u>POINT-SLOPE FORM: </u>
, where 
represents the y-coordinate of your point, 
represents the x-coordinate of your point, and 
represents the slope
Answer:
True
Step-by-step explanation:
If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²
c is the largest side and a and b are the two smaller sides of the triangle.
So if this is true then √72² + 154² should be 170:
170² = 72² + 154²
28900 = 5184 + 23716
28900 = 28900
So we have proved using Pythagoras theorem that the triangle is a right angled triangle.
