Answer

The y-intercept = 2

Step-by-step explanation

The slope and y-intercept form of the equation of a straight line is given as

y = mx + b

where

y = y-coordinate of a point on the line.

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

b = y-intercept of the line.

So, we just have to write the given equation in this form and the y-intercept will become apparent.

x + 4y = 8

4y = -x + 8

Divide through by 4

(4y/4) = (-x/4) + (8/4)

y = -0.25x + 2

Comparing this with y = mx + b

We can see that

b = y-intercept = 2

Hope this Helps!!!
