Question

Find the equation of this line.
[?]
x + [ ]
y

Answer 1

y = ½x + 1

Explanation:

the line pass through (x1,y1) as (-2,0) and (x2,y2) as (0,1) so the line equation can be determine by

`(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)`

(y-0)/(1-0) = (x-(-2))/(0-(-2))

y = (x+2)/2

y = ½x + 1

Answer 2

Explanation:

In a equation of a line

y=mx+c

Let's take two points from the graph (0,1) and (4,3)

Slope=m= (3-1/4-0)= 2/4=1/2

C= 1

y=½x+1
