The top of a ladder is 4m up a vertical wall. the bottom is 2m from the wall. the coordinate axes are the wall and the horizontal ground.
a)find the equation representing the ladder.
b)a square box just fits under the ladder. find the coordinates of the point where the box touches the ladder.

Part a)

Part b) The coordinates of the point are

Step-by-step explanation:

Part a) Find the equation representing the ladder

we have the ordered pairs

(0,4) and (2,0)

Find the slope

Find the equation of the line in slope intercept form

we have

substitute

Part b) A square box just fits under the ladder.Find the coordinates of the point where the box touches the ladder.

If the box is a square

the x-coordinate of the point where the box touches the ladder must be equal to the y-coordinate

x=y

substitute

therefore

The coordinates of the point are

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
