Answer:
x = 2.5
Explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
here m = - 2 and c = 5, so
y = - 2x + 5 ← equation of line
To find the x- intercept let y = 0, that is
- 2x + 5 = 0 ( subtract 5 from both sides )
- 2x = - 5 ( divide both sides by - 2 )
x = 2.5 ← x- intercept ⇒ (2.5, 0 )
