Answer:
w = 5
y = 4
Step-by-step explanation:
w+y=9
3w-y=11
4w = 20
w = 5
y = 4
9x +5y= -45
put in standard form
y= mx+b
coefficient of x is the slope, b is the y intercpept
5y= -9x -45
y= -9/5 x -45
graphing will start at -45 on the y axis
from that point go down 9 to the right 5 for the slope continue and graph minimum
2 points to draw the line
hope this helps
It's up to you what you chose for A and or B because 0 slope of a line is for a flat horizontal line and an undefined slope is for a flat vertical line
With this information you should chose D regardless but that's also up to you I would though and E is correct.
Answer:
Equation = (x - 6 )² + ( y + 3 )² = 9
Step-by-step explanation:
The circle passes through ( 6, 0) and ( 6 , -6)
They are the coordinates of the diameter.
Using this we can find the centre of the circle.
<u>Find the centre of the circle.</u>
Centre of the circle is the mid- point of (6, 0) and ( 6, -6)


<u>Find the radius of the circle.</u>

Diameter is the distance between the points (6 , 0) and ( 6, - 6)


Therefore,

<u>Standard equation of a circle:</u>

Therefore , equation of the circle ;
