Algebra Difficulty 1.2 Junior Find the answer Canada

Cynthia graphs a sequence of points. The first point has
coordinates $(-3,0)$ , the second
point has coordinates $(-2,2)$ , and
the third point has coordinates $(-1,4)$ . Each point after the first is 1
unit to the right and 2 units above the previous point. What is the
fourth point that Cynthia graphs?

Pick one

Solution

The fourth point is $1$ unit
to the right of $(-1,4)$ and so its
$x$ -coordinate is $1$ unit greater than $-1$ , which is $-1+1=0$ .

The fourth point is 2 units above $(-1,4)$ and so its $y$ -coordinate is $2$ units greater than $4$ , which is $4+2=6$ .

The fourth point that Cynthia graphs is $(0,6)$ .
