Answer
To find another point on the line, we can use the point-slope form of a linear equation, which is given by:
where \( (x_1, y_1) \) is a point on the line and
is the slope. In this case, the point \( (2, 1) \) is on the line, and the slope
is
.Let's find another point by choosing a different
-value. We can choose an
-value that makes calculations simple. Let's choose
.Substitute
into the point-slope formula:
Calculate the right side:
Add 1 to both sides to solve for
:
So, another point on the line is \( (5, -4) \).Therefore, the two points Shamya can use to graph the line are \( (2, 1) \) and \( (5, -4) \).
