Answer:
y = [tex]\frac{2}{3} x + 9[/tex]
Step-by-step explanation:
I. If y = mx + b
when y is output, x is input , m is slope and b is addition
so y - 2x = 9
y = 9 + 2x
y = 2x + 9
Replace 2 with [tex]\frac{2}{3}[/tex]
y = [tex]\frac{2}{3} x[/tex] + 9
Answer:
a is 3
Step-by-step explanation:
[tex]ay - 2x = 9 \\ ay = 2x + 9 \\ y = \frac{2}{a} x + \frac{9}{a} [/tex]
General equation:
[tex]{ \bf{y = mx + c}}[/tex]
m is slope; m = ⅔
by comparison:
[tex] \frac{2}{3} = \frac{2}{a} \\ \\ 2a = 6 \\ a = 3[/tex]
