Question

Find the equation of the line parallel to y=x+1 and that passes through the point (-2,-1)

Answer 1

Its the same line y = x + 1.

Explanation:

The slope of the line = slope of y = x + 1 which is 1.

Using the point-slope form of a line:

y - y1 = m(x - x1) and substituting the given values:

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

y + 1 = x + 2

y = x + 1

Answer 2

y = x -1

Explanation:

parallel lines have the same gradient therefore = x.

y intercept of second is -1
