Answer:
b = 3/4
Step-by-step explanation:
The linear equation has the following general form.
y = a.x + b
where,
y is the dependent variable
a is the slope
x is the independent variable
b is the y-intercept
The slope is 1/4, so
y = 1/4 . x + b
We have the ordered pair (0.2, 4/5). We can find the y-intercept by replacing these values in the previous equation.
y = 1/4 . x + b
4/5 = 1/4 . 0.2 + b
b = 3/4
The final equation is
y = 1/4 . x + 3/4
