A tree 5ft grows and average of 8in each year . Write and graph an equation to model the trees height h after x years

Question

anonymous · Answer

Easy! Well 5 ft would be your constant or y intercept. This means your graph starts a 0,5. The 8 is the coefficient of h. Do you get the equation now? (: Let me know if you want me to continue if you don't understand.

anonymous · Answer

Are we cross multiplying to get to h? And yes continue please

anonymous · Answer

Okay so your equation would be h=8x+5.
Height in x years. Get it?

anonymous · Answer

h = 8x + 60

anonymous · Answer

And when we graph it will it go up by 8's on the h side and 1(years ) on the x side ?

anonymous · Answer

Not sure how to graph

anonymous · Answer

h = 8x + 60
That's your graph, see?

anonymous · Answer

Wait... why is it +60? Isn't it 5 Brightly?

anonymous · Answer

No.

anonymous · Answer

Convert 5 ft to 60 inches.

anonymous · Answer

Slope = m = 8
Y-Intercept = b = 60

anonymous · Answer

Wow! Yup I didn't notice that. You are correct (:
