Question

2';

2. Write the equation of a line in slope-intercept form passing through (4, 5) and (6, 8)

Answer 1

@AriPotta

Answer 2

first we need to find the slope

Answer 3

so 8-5/6-4

Answer 4

yes, which simplifies to...?

Answer 5

3/2

Answer 6

yes. now we can put it into point-slope form

Answer 7

wait but all 4 answers are like this look

Answer 8

yes, we have to put it into point-slope before we can put them into slope-intercept

Answer 9

ok

Answer 10

so what's our point-slope form look like?

Answer 11

you can use either given point

Answer 12

m=3/2

Answer 13

yea, that's the slope, but what does our equation look like

Answer 14

im confuse about tht already lool

Answer 15

we'll use the first point (4,5) so use that and m=3/2 and put it into point-slope form

Answer 16

m=3/2+4

Answer 17

no, into point-slope form...you forgot what that was? it's y - y1 = m(x - x1)

Answer 18

y-5=m(x-4)

Answer 19

yes, but we know that m = 3/2

Answer 20

y=3/2x+1

Answer 21

y = 3/2x - 1

Answer 22

why -?
