Question

how do you use the slope-intercept form to write an equation of a line given its slope and y-intercept?

Answer 1

y = mx+b is the general slope intercept form

m is the slope
b is the y-intercept

Answer 2

example:

y = 3x+10 is in y = mx+b form where m = 3, b = 10

the slope is m = 3
the y-intercept is b = 10

Answer 3

how do you use the slope-intercept form to write a line written in slope-intercept form?

just plug in the values then
