Answer:
so you would use y=mx+b right? so if you would use this you would need to plug in x and the y-intercept so...
Step-by-step explanation:
x=1/.5
y= is the y-intercept!
Answer: a = -4
Step-by-step explanation:
Let x be the first number each pair and y is the second of each
As you see 1x is 3y
And. 2x is 3*3y= 9y
3x = 3*3*3y= 27y
Last 4x =3*3*3*3y= 81y
So y = 3^x
