I need to find the slope, vertical intercept and horizontal intercept of these 3 linear functions:

y=5x-15

y=7-x

4x=2y=12

These are in y=mx+b form where m=slope

sometimes b=0

vertical intercept means the y-intercept and the horizonatl intercept is the x intercept so the x intercept is when y=0 and the y intercept is when x=0 so the first one is

y=5x-15

slope=5

y-intercept=-15

x-intercept=3

y=7-x

this can be written as

y=-1x+7

slope=-1

y-intercept=7

x-intercept=7

4x=2y=12

we must get it into slope intercept form

divide the whole thing by 2x=y=12

we can disregard the 12 and get

2x=y or y=2x+0

slope=2

y-intercept=0

x-intercept=0
