Question

Graph the line that passes through the points (-9,8) and (-7,8) and determine the equation of the line

Answer 1

ans=y=8

• look for the gradient

`(change \: in \: y)/(change \: in \: x?)`

• change in y

8-8=0

• change in x

-7--9=2

hence the gradient is 0÷2=0

looking for the equation

gradient(0)=

`(y - 8)/(x - - 9?)`

so..,0=y-8

hence the equation is y=8
