Answer
Point A:
$y=-5x$
$y=-5(1)$
$y=-5$
Point B:
$y=-5x$
$y=-5(0)$
$y=0$
Point C:
$y=-5x$
$y=-5(-1)$
$y=5$
Work Step by Step
To get the coordinates of point A, substitute the given x-value of 1 into the given equation $y=-5x$ to get the y-value of y=-5. Hence, we know that when x is 1, y is -5. i.e (1,-5) is a point on the line.
To get the coordinates of point B, substitute the given x-value of 0 into the given equation $y=-5x$ to get the y-value of y=0. Hence, we know that when x is 0, y is also 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 $y=-5x$ to get the y-value of y=5. Hence, we know that when x is -1, y is 5. i.e (-1,5) 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 $y=-5x$.
