Question

Find the equation of the line shown

Answer 1

y=x+1

Explanation:

find 2 points which they are on the line

for example:

f(0)=1 Basically shows: x=0,y=1

f(1)=2 Also: x=1,y=2

Find the slope of the line

m=∆y/∆x

`m = (2 - 1)/(1 - 0) = 1`

Also we know:

y-y0=m(x-x0)

Put one of the points instead of y0 & x0:

y-1=1(x-0)

y=x+1

(An easy way is: put 2 points of the line in this equation y=ax+b and find a and b)
