Please help me figure out what the slop-intercept form is. Also, what is the solution to the system?

Misha Larkins [42]

Answer:

p= y=6x+2

Q= y=-2x+2.5

Step-by-step explanation:

the formula is y=mx+b

M=slope

B=y-intercept

The y-intercept is the number that your line goes through

The slope is two ordered pairs where you use the formula rise over run to find your slope.
