Question

Write the equation of the line with a slope of 1/5 that passes through the point (20,5)

Answer 1

`y = (1)/(5) x + 1`

Explanation:

the general equation of a line is y=mx+c

because the slop is 1/5, the equation of this line would be

`y = (1)/(5) x + c`

with the coordinates (20,5) , take 20=x and 5=y

and substitute these values into the equation above.

you should get:

5= 4 + c

so c = 1

therefore, the equation of the line is:

`y = (1)/(5) x + 1`
