Question

A line has a slope of -3 and a y intercept of 3. What is the x-intercept of the line?

O-9
0-1
O 1
09

Answer 1

The answer is (0,1)

Explanation:

the slope is -3, so it moves down 3 spaces (y) for every space going right (x), so it would go right one and down 3 from (3,0) to get to (0,1)

Answer 2

The answer is option 3.

Explanation:

First, you have to form an equation in a slope-form, y = mx + c where m represents gradient and c is y-intercept. Then substitute the following values into the equation :

`y = mx + c`

Let m = -3,

Let c = 3,

`y = - 3x + 3`

Next, in order to find the x-intercept, you have to let y equals to 0 as the line touches x-axis, y will be 0 :

Let y = 0,

`- 3x + 3 = 0`

`- 3x = - 3`

`x = - 3 / - 3`

`x = 1`
