Write an exponential equation in the form y = ab* whose graph passes through points (2, 18) and (5, 60.75).

DochEvi [55]

Let $y=ab^x,$ as described in the problem statement. Plugging in $x=2$ and $x=5$ gives us the equations $18=ab^2$ and $60.75=ab^5.$ Since $a,b$ are nonzero, we divide the second equation by the first to get $\frac{27}{8}=b^3,$ which means that $b=\frac{3}{2},$ after taking the cube root. Plugging this value for $b$ into the first equation, we now have $18=a(3/2)^2=\frac{9a}{4}.$ Solving gives $a=8,$ and our desired exponential equation is $\boxed{y=8\left(\frac{3}{2}\right)^x}.$

Math help again please

vovangra [49]

Hey there! :D

First, find the slope.

m= (y2-y1)/(x2-x1) I'm using points (0,3) and (1,5)

m=(5-3)/(1-0)
m= 2/1
m=2

Now, plug that into point slope. Use point (1,5) m=2

y-y1= m(x-x1)

y-5= 2(x-1)

Distribute.

y-5=2x-2

Add 5 to both sides.

y=2x+3 == equation of the line in slope intercept form. y=mx+b

I hope this helps!
