Use distrubutive property <em>a(b + c) = ab + ac</em>

6(5r - 4) - 2(r - 7s - 3)

= (6)(5r) + (6)(-4) + (-2)(r) + (-2)(-7s) + (-2)(-3)

= 30r - 24 - 2r + 14s + 6

= (30r - 2r) + 14s + (-24 + 6)

<h3>= 28r + 14s - 18</h3>

Find the slope of the line going through the points (11,5) and (20,5)
Pani-rosa [81]
So remember the formula for working out the slope:

(y2 - y1) ÷ (x2 - x1)

We already know two points:

(11, 5) and (20, 5) (Remember points are like (x, y)


Therefore y2 = 5 and y1 = 5 and x2 = 20 and x1 = 11

Substitute these into the formula from the start:

(y2 - y1) ÷ (x2 - x1)
(5 - 5) ÷ (20 - 11)
0 ÷ 9

And we can determine the slope is equal to 0 as 0 ÷ 9 = 0
