Answer:
y+5x=31
Step-by-step explanation:
m=-5( coefficient of x wen y is subject)
y-y1=m(x-x1)
y+9=-5(x-8)
y+9=-5x+40
y+5x=40-9
y+5x=31
La primera es 264.6
La segunda es 125
Si no me equivocó
Answer:
No, the equation does not represent a direct variation.
Step-by-step explanation:
The answer is immediately evident: NO. The reason for this is that no direct variation equation includes a vertical intercept.
Here 2y = 5x + 1 becoems y = (5/2)x + 1/2; the y-intercept 1/2 is problematic.
If we were to drop the constant 1, then 2y = 5x, or y = (5/2)x; this represents direct variation with the constant of proportionality 5/2.
