Answer
Point A:
$y=-4x$
$y=-4(1)$
$y=-4$
Point B:
$y=-4x$
$y=-4(0)$
$y=0$
Point C:
$y=-4x$
$y=-4(-1)$
$y=4$
Work Step by Step
To get the coordinates of point A, substitute the given x-value of 1 into the given equation $y=-4x$ to get the value of y=-4. Hence, we know that when x is 1, y is -4. i.e (1,-4) is a point on the line.
To get the coordinates of point B, substitute the given x-value of 0 into the given equation $y=-4x$ to get the value of y=0. Hence, we know that when x is 0, y is 0. i.e (0,0) is a point on the line.
To get the coordinates of point C, substitute the given x-value of -1 into the given equation $y=-4x$ to get the value of y=4. Hence, we know that when x is -1, y is 4. i.e (-1,4) is a point on the line.
Find the three points using the x and y values that you found, i.e graph points A, B and C. Using a ruler, draw a straight line passing through all three points to graph the equation of $y=-4x$.
