Question

A line has a slope of -2 and a Y intercept of -3. Graph the line using the slope and y-intercept. Which of the following points lie on the same line

Answer 1

(-1.5,0) , (-6,9) , (3,-9)

Explanation:

I had the same question :)

Answer 2

Greetings!

Answer:

(1.5 , 0) , (-6 , 9) , (3 , -9)

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)

Hope this helps!
