Answer:
8 = r; (9, 8)
Explanation:
-y₁ + y₂\-x₁ + x₂ = m
-2 + r\3 + 9 = ?\12
-2 + r = 6
+2 + 2
__________
r = 8
The reason why the expression has to equal 6 is because 6⁄12 simplifies to ½, and the numerator has to be a six in order to get the <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] of ½, so there you have it.

third option
Step-by-step explanation:
Given
3
Multiply each element in the matrix by 3
=
[(5-5)^2-15/3]•-6•-2
[0^2-15/3](-6)(-2)
[0-5](-6)(-2)
[(-5)(-6)](-2)
30•-2
ANSWER:-60
0.4x^3 - xy.
2/7x(1.4x^2-3.5y) Distributing the2/7x over the parentheses:
= 2/7 * 1.4 x^3 - 2/7 *3.5xy
= 0.4x^3 - xy
