Question

Write an equation in point-slope form for the line through the given point with the given slope. 
(–7, 9); m = 4/5

anonymous · Answer

y + 7 = 4/5(x – 9) 
y – 7 = 4/5(x + 9) 
y – 9 = 4/5(x + 7)
 y + 9 = 4/5(x – 7)

...And lol if you have time could you walk me through this question as well?

The table shows the height of a tree as it grows. 
What equation in slope-intercept form gives the tree's height at any time? 
 Time       Height
(months) (inches) 
2              14 
4              23
 6             32
 8             41

 y = 9x + 2 
y = 9/2x + 5 
y = 9/2x 
y = 5x + 9/2

Do you know point slope form?

anonymous · Answer

Not really :(

anonymous · Answer

Sorry. I hate math and I suck at it lol

anonymous · Answer

$$y-y _{1}=m(x-x _{1})$$
For m, plug in the slope. For y1, plug in the y coordinate (9), and for x1, plug in the x coordinate (-7)

anonymous · Answer

Let me know what you get when you plug it all in

anonymous · Answer

I'm still kind of confused.. I'm so sorry

anonymous · Answer

Do you see the equation i posted?

anonymous · Answer

y - 9 = m(x-7)

anonymous · Answer

the first part is perfect, but it's not supposed to be -7. Its a double negative, which makes it a +7
