What is the y-intercept of a line that has a slope of 1/4 and passes through point (8,3)?

The slope-intercept form: y = mx + b

m - a slope

b - y-intercept

We have a slope m = 1/4. Substitute: y = 1/4 x + b

We know, the line passes through point (8, 3) → x = 8, y = 3.

Put the values of x and y to the equation of the line:

1/4 · 8 + b = 3

2 + b = 3 |-2

b = 1

y-intercept is (0, 1)

so, converting firstly the mixed fractions to improper fractions and then "adding".

answer: group b.
