Question

What is the equation of the line with an x intercept of -1 and y intercept of 2

Answer 1

The correct answer is y=2x+2

Answer 2

Equation of line is given by:

y=2x+2

Explanation:

The equation of a line is given by:

y=mx+c

where c is the y-intercept and m is the slope

y-intercept is given to be 2 i.e. c=2

Now, we have to find the value of m

x-intercept is the value of x where y= -1

0= m(-1) + 2

or -m+2=0

or m=2

Hence, equation of line is given by:

y=2x+2
