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

The answer is option 3.

Step-by-step 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 :

Let m = -3,

Let c = 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,

b) well because you get well
