Answer:
Option C is correct.
Equation of a line 
passing through (0,6) and (9,0).
Explanation:
Given the two points (0, 6) and (9 ,0).
To find the equation for the given two points 
and 
is,
; where m is the slope and is given by:
First find the slope m:
Substitute this value in equation of line:
or
⇒
Therefore, the equation for the given point is:
Answer:
11 calls
Step-by-step explanation:
She has already spent 42 min. Also she wants to talk for 2 min per call. We can change calls on x. So, only 2x min for her calls left.
42 + 2x = 64
2x = 64 - 42
2x= 22
x=11
Answer: 11 calls
Answer:
Get a line of which you want to know the slope. Make sure that the line is straight.
Pick any two coordinates that the line goes through. Coordinates are the x and y points written as ( x, y ).
Pick which point's coordinates are dominant in your equation. ...
Set up the equation using the y-coordinates on top and the x-coordinates on bottom.
You go up 4 times and go to the left 2 times so the slope would be 4/-2
Answer:
x=45
Step-by-step explanation:
An entire triangle is 180 degrees and you already know that one angle is 90 degrees. 180 - 90 is 90. Now you have the equation 2x=90.
You then divide each side by 2 to get the x by itself which leaves you with x=45.
