Question

what is an equation of the line that passes through the points (1,3) and (8,5)

Answer 1

One sec

Answer 2

y = 2/7x + 2

Answer 3

or in point slope
y - 3 = 2/7 (x - 1)

Answer 4

first you need to work out the slope
there formula is

\[m=\frac{ y_{2}-y_{1} }{ x_{2}-x_{1} }\]

where m is the slope

(x1,y1)=(1,3)
(x2,y2)=(8,5)

now we must work out the equation of the line the formula is

\[y-y_{1}=m(x-x_{1})\]
