Answer:
(1.5 , 0) , (-6 , 9) , (3 , -9)
Step-by-step explanation:
First, you need to find the equation of the line, which is:
y = mx + c
Where m is the gradient (or slope) and c is the y-intercept. Simply replace these values with the one given to you:
y = -2x -3
Now, simply draw this line by finding two points,
x = 0
y = -2(0) - 3
y = -3 when x = 0
When x = 3
y = -2(3) - 3
y = -9 when x = 3
Now you can use these points to plot the graph. (attacthed a screenshot of it)
Now simply find which given co-ordinates fit on the line. The points on the line are:
(1.5 , 0) , (-6 , 9) , (3 , -9)
