Question

Help! Fan and medal:
what is the slope intercept form of a line if the line goes through the points 65,65 and 74,74?

Answer 1

I got to this answer but I'm pretty sure that's not right:

M = 66-74/65-74 = -8/-9 = 8/9

y – y1 = 8/9(x – x1)
y – 66 = 8/9(x – 65)
y = 8/9 x -65 + 66
y = 8/9x + 1

Answer 2

HI!!

Answer 3

i think you made a typo

Answer 4

Where?

Answer 5

\[\frac{74-65}{74-65}\] both x and y in the first one where 65 in the question

Answer 6

oops the real question is 65,66

Answer 7

oh

Answer 8

hint: remember a(b+c)=ab+ac not ab+c

Answer 9

then your slope is right, but your y intercept is wrong

Answer 10

damn that distributive law !!

Answer 11

@freckles
so it would be:
M = 66-74/65-74 = -8/-9 = 8/9

y – y1 = 8/9(x – x1)
y – 66 = 8/9(x – 65)
y -66 = 8/9x -8/9(65)
y = 8/9x -57.77 +66
y = 8/9x -57.77 +66
y = 8/9 - 8.23

Answer 12

\[(65,66) \text{ and } (74,74) \\ m=\frac{74-66}{74-65}=\frac{8}{9} \\ y-y_1=m(x-x_1) \\ y-66=\frac{8}{9}(x-65) \\ y-66=\frac{8}{9}x-\frac{8}{9} \cdot 65 \\ y-66=\frac{8}{9}x-\frac{520}{9} \\ y=\frac{8}{9}x-\frac{520}{9}+66 \\ y=\frac{8}{9}x-\frac{520}{9}+\frac{594}{9}\]
\[y=\frac{8}{9}x+\frac{594-520}{9}\]
You know if you are suppose to leave it in fractional form
I will let you do 594-520 :)

Answer 13

fractional form also exact form since you sorta rounded 8*65/9

Answer 14

Okay thanks so much
