Answer:
y=[-2]x[+][5]
Step-by-step explanation:
m= -2
Using the point (1,3) Find the value of b
3= -2(1)+b
3= -2+b
+2 +2
---------
5=b
y= -2x+5
Is there any multiple choices if so can i see them
Answer:
and 
Step-by-step explanation:
We have been given the parabola with vertex (1, -9) and y intercept at (0, -6).
Now we need to find the x-intercepts of that parabola. So first we begin by finding the equation of parabola using vertex formula:

Vertex for this formula is given by (h,k)
Compare that with given vertex (1,-9), we get: h=1, k=-9
So plug these into vertex formula:
...(i)
Plug given point (0, -6). into (i)





Plug a=3 into (i)

Now to find x-intercept, we just plug y=0 and solve for x






Hence final answer are
and 
Um I think the first one is non proportional and the 2nd one is proportional y is 5 times x the 5 might be a negative
Your answer would be 4:$7.20 because 2027-2002 is 25 years and 0.24(25)+1.20 is $7.20
