Question

(2,5) and (3,7)

slope: 2

what is the point slope form ?

what is the slope intercept form ?

Answer 1

equation in slope intercept form:

`y = 2x +1`

given coordinates:

`(2,5) and (3,7)`

find slope,m:

`(y2 - y1)/(x2-x1)= (7-5)/(3-2) = 2`

using the formula:

`y - y1= m(x-x1) : y-5=2(x-2)`

`y = 2x +1`

Answer 2

equation in slope intercept form: y = 2x +1

Explanation:

• given coordinates = (2,5) and (3,7)

• find slope,m = (y2 - y1) / (x2 - x1)

= (7 - 5) / ( 3 - 2)

= 2

• using the formula: y - y1= m( x - x1 )
  : y - 5 = 2( x - 2 )

: y = 2x +1
