Question

If a line crosses the y-axis at (0,1) and has a slope of 4/5 what is the equation of the line

Answer 1

y = (4/5)x + 1

Explanation:

The slope-intercept form of the equation of a line is

y = mx + b, where m is the slope and b is the y-intercept.

We are given m = 4/5, and are given a point (x, y) of (0, 1), so plug those in and solve for 'b'

1 = (4/5)(0) + b

1 = b

So the equation is y = (4/5)x + 1
