Want does the y- intercept mean ?

The y-intercept is the y value  of an equation on  a graph or cordinate grid For example y=mx+b, b would be the y-intercept. Another example, y=2x-2, -2 would be the y-intercept and you would place a point on -2 and go up 2 right 1 because of the slope 2. I hope this helps you to better understand the y-intercept. 

It is important because sometimes ur dna needs to multiply

step-by-step explanation:

when the line is solid:

it's either < or >

when the line is dashed:

it's either < or >

this > inequality sign means:

greater thanmore thanaboveexceeds

this < inequality sign means:

less thanfewer thanbelow

this > inequality sign means:

greater than/equal tono less thanat leastminimum of

this < inequality sign means:

less than/equal tono more thanat mostmaximum of

about the problem:

since the line is solid, that means it's either < or >

srry i'm not done ! i'll
