Answer:
x - intercept = 1
Explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3 and c = 3, thus
y = - 3x + 3 ← equation of line
The x- intercept has a y- coordinate of zero.
let y = 0 in the equation and solve for x, that is
- 3x + 3 = 0 ( subtract 3 from both sides )
- 3x = - 3 ( divide both sides by - 3 )
x = 1 ← x- intercept
