-- As the line moves from left to right, it rises. So you know that
its slope is positive.
(All 4 choices have positive slopes, so that doesn't help.)
-- From the place where the line crosses the x-axis to the place
where it crosses the y-axis, it moves 2 units forward and also
rises 2 units. So you know that its slope is (2/2) = 1 .
(A. and C. both have slopes of 2, so it can't be either of those.)
(B.and D. both have slopes of 1,so it could be either of those.)
-- The line does not go through the origin. So you know that
its y-intercept is not zero.
(A. has no y-intercept, so that can't be it.)
-- The line crosses the y-axis at y=2, so you know that its y-intercept is 2 .
(B. has y-intercept of -2, so that can't be it.)
(C. and D. both have y-intercept of 2, so it's one of those.)
(But the slope has to be 1, and C. has slope of 2.)
(So it must be D.)
