Cartesian Plane

Draw the x-y axes. (Remember that the x-axis is horizontal, the y-axis is vertical and the two axes intersect at the origin)

Plot the five following points on the Cartesian Plane.

(3, 2), (-1, 4), (-3, -10), (0, 3) and (-4, 0)

Write down the coordinates of A.

(a)  

Write down the coordinates of B.

What can we say about these points?

(0,3), (0,-2), (0,0), (0,5)

What can we say about these points?

(3,0), (-2,0), (0,0), (5,0)

The function has an input x. The input x is multiplied by 4 followed by an addition of 3. The output is y. Write down the equation linking y and x.

A function has an input x. 2 is subtracted from the input x followed by a division of 8. The output is y. Write down the equation linking y and x.

A function has rule: $$y=2x+2$$ . Find the value of y when x = -1.

A function has rule: $$y=2x+2$$ . Find the value of x when y = 4.
