Question

A line has a slope of 1/4 and passes through the point (0.2. 4/5).

Find the value of b, the y-intercept.
b=

Answer 1

0.75

Answer 2

The value of the y-intercept b is 0.75

Explanation:

Here, we want to find the value of the y-intercept

The equation of the line can be written as;

y = mx + b

where m is slope and b is the y-intercept

so y = 1/4x + c

To get the value of b , we substitute for x and y using the given point

4/5 = 1/4(0.2) + c

Multiply

0.8 = (0.25)(0.2) + b

0.8 = 0.05 + b

b = 0.8 - 0.05 = 0.75
