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

Explanation:

A line has a general equation of

where b is the y-intercept and slope of m.

Since is the value of y when , it is the point of intersection of the line with the y-axis, hence the y-intercept is .

We are given the slope is

So the equation of the line is

replace   c   with   a   and simplify.

a = c , b = a, q = n , 2 , a = c , 900 b= a , 700 , q = n , 600 , 2 = b o t h , b = a , q = n
