Leni [432]
Y=-3x+2:
Already in slope intercept form
Graph by plotting a point on (0,2)
Then move 3 points up and 1 to the right and plot the point and keep doing that a couple times

-3x-y=-2:
Add -3x on both sides
The result would be
-y=3x-2
Divide everything by negative 1
Y=-3x+2

Both equations are the same so they are the same line

Part 1: Multiple Choice
Keith_Richards [23]

Option C: (0,125) is the y - intercept.

Explanation:

The given function is f(x)=x^3-5x^2-25x+125

We need to determine the y - intercept.

<u>The value of y - intercept:</u>

The y - intercept is the value of y when x = 0

The y - intercept of the function can be determined by substituting x = 0 in the function.

Hence, let us substitute x = 0 in the function f(x)=x^3-5x^2-25x+125, we have,

f(x)=(0)^3-5(0)^2-25(0)+125

Simplifying the terms, we get;

f(x)=0-5(0)-25(0)+125

f(x)=0-0-0+125

f(x)=125

Thus, the value of y is 125.

Hence, the y - intercept is 125.

Therefore, the coordinates of the y - intercept are (0,125)

Hence, Option C is the correct answer.
