This isn’t an answer but go on desmos and you should be able to find the graph
From the equations given above, you can graph them by the slope and the y-intercept. I will be solving this by substitution method. It will be giving the same values as with graphing. We do as follows:
-2x + 30 <span>= -x + 21
-x = -9
x = 9
y = -9+21 = 12
Hope this helps. Have a nice day.

Answer: y= -3/2x
Explanation:
3x+ 2y- 6
→ 2y= -3x+ 6
→ y= -3/2x+ 3
Parallel to y= ax+ b is to have the same slope (ax) and have a different y- intercept.
For this equation, y= -3/2x + 3, it is y= -3/2x because the line has to pass through point (0,0).
Since pi is irrational and it is used in the formula, we cannot give an exact answer except in terms of pi (we can give an aproxamation using 3.14 =aprox pi, but it is not exact)
ok
circumfernce=2pir
r=15
circumference=2pi15
circumference=30pi
exact=30pi cm
if you want to aprox pi=3.14 then
aprox circumfernce=94.2 cm
