Answer:
-4x + y + 6z
Step-by-step explanation:
Combine like terms (Terms with the same variable):
(2x + 5y - z) + (-6x - 4y + 7z)
Add straight across:
2x - 6x = -4x
5y - 4y = y
-z + 7z = 7z - z = 6z
-4x + y + 6z is your answer.

Step-by-step explanation:
gradient = slope or several other words.
it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.
it is represented by the ratio
(y coordinate change / x coordinate change)
when going from one point on the line to another.
in our case, when going from A to B we have
x changes by -2k (from 3k to k).
y changes by -11 (from 8 to -3).
so, the gradient or slope is
-11/-2k = 3
11/2k = 3
11 = 3×2k = 6k
k = 11/6
A = (33/6, 8) = (11/2, 8)
B = (11/6, -3)

Answer:
y - 5 = 1/3(x - 0)
Step-by-step explanation:
the formula for point-slope form is y2 - y1 = m(x2 - x1), where m is the slope, y1 is the y coordinate and x1 is the x coordinate
so just plug in the values into the equation:
y - 5 = 1/3(x - 0)
if you want it in slope-intercept form, the formula is: y = mx+b, where mx is the slope and b is the y intercept. it would look like the following:
y = 1/3x + 5
