Question

Simplify the following expression.
8x - 10y + 5z - 5x - 16y + 6z

3x - 6y + 11z

13x - 6y + 11z

13x - 26y + 11z

3x - 26y + 11z

Answer 1

Do u know u can add like terms

Answer 2

you need to find the slope here
[if you are given the slope you know m
as in
y=mx+b]

slope =rise/run
[change in y]/[change in x]
(y1-y2)/(x1-x2)

either point can be 1 or 2
whichever is easier to subtract

(8-2)/(-5+3)
6/-2

slope= -3

so you start with y= -3x

to intercept a point
subtract the given values from their relative x and y variable

(-3, 2) and (-5, 8)

(y-2)= -3(x+3)
y-2 = -3x-9
y= -3x-7

or
y= -3x
(y-8)= -3(x+5)
y-8= -3x-15
y= -3x-7

Answer 3

I dont know what r u doing @abayomi12

Answer 4

8x - 10y + 5z - 5x - 16y + 6z
8x-5x-10y-16y+5z+6z
3x-26y+11z
