The required 3 more coordinates are (0, 2), (1, 3/2), and (2, 1).
Given that,
To determine points using a slope of -1/2 and the point (-2,3).
<h3>What is coordinate?</h3>
Coordinate, is represented as the points on the x-axis and y-axis of the graph.
Here,
using the slope-intercept form of the equation,
y = mx + c
we have a point (-2, 3) and m = -1/2
Put point and slope in the equation,
3 = -1/2 * -2 + c
c = 3 - 1
c = 2
Now equation would be
y = -1/2x + 2
Now,
For x = 0
y = 2
Coordinate will be (0,2)
For x = 1
y = -1/2 + 2
y = 3/2
Coordinate will be (1, 3/2)
For x = 2
y = -1/2 * 2 + 2
y = 1
Coordinate will be (2, 1)
Thus, the required 3 more coordinates are (0, 2), (1, 3/2), and (2, 1).
