A1 means the first number
so a1 is (-4)
Answer:
Should be, (-3,5) (if rise over run aka y,x)
Step-by-step explanation:
When attempting to find a slope like this, you need to locate pretty points. Pretty points are any time the line meets an exact corner on the box. If you look at -3,1, you can see the line makes a pretty point there. Then, try to find the next one, which is at 2,-3. Once you found these pretty points, try to connect them by drawing a line towards each other THAT IS STRAIGHT until those intersect. Where they intersect is where the slope of the line is. In this case, when I drew the line, they met at <em>down three</em>, <em>over (right) 5.</em>
10, 5, 20, 10, 40, 20, 80, 40, 160, 80,
Next Three Numbers: 20, 80, 40
Pattern: Take half of the first term. 1/2 of 10 = 5 which is the second term.
Next, multiply the second term by 4. 5 times 4 = 20
Divide 20 by 4 to get 10
Multiply 10 by 4 to get 40
---------------
Take half of 40 to get 20 (the first of the three missing terms)
Multiply 20 by 4 to get 80 (the second missing term)
Multiply 80 by 1/2 to get 40 (the third missing term)
First, you distribute the 3 into the brackets,
<span>3(x - 2) + 5x
=</span><span>3(x) + 3(-2) + 5x
=3x - 6 + 5x
Adding the like terms, 3x and 5x, gives you
=8x - 6</span>
