Substitute the value for y as 450

450=-5x+1

Solve for x

450-1=-5x

449=-5x

89.8=-x

x=-89.8

Answer:

x = 290

Step-by-step explanation:

The x- intercept is the point on the x- axis where the line crosses.

substitute y = 0 into the equation and solve for x

- 5x + 1450 = 0 ( subtract 1450 from both sides )

- 5x = - 1450 ( divide both sides by - 5 )

x = 290 ← x- intercept

line crosses x- axis at (290, 0)
