Evaluate -a -8b when a=9 and b=3 i need it quick

Start with -a -8b.

Replace a by 9 and b by 3:      -(9)-8(3)

Order of operations rules require that we mult. before adding or subtracting.

Therefore, we obtain -9 - 24.

Combining these two terms results in the desired value:  -33.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
