Using the slope-intercept form of y = mx + b, just plug in for the values given by the graph.

Your Y-intercept (0, y), you plug in the y value as B. M is where you put your slope.

So for the second one (top right), you have a Y-int of -2 or (0, -2) and a slope/m of 1/1 = 1. So your equation would be y = 1x - 2 or y = x - 2.

One number is 8 more than another. If the sum of the two numbers is 166, find the two numbers.

Igoryamba

$\bf \underline{Given : }$

One number is 8 more than another.

Sum of the two numbers is 166.

$\bf \underline{To \: find \: out : }$

Find the two numbers.

$\bf \underline{Solution : }$

Let the one number be x.

Then,another number = x + 8

<u>According to the question </u><u>,</u>

Sum of the two numbers is 166. [ Given ]

$\sf\implies \: x + x + 8 = 166$

$\sf \implies \: 2x + 8 = 166$

$\sf \implies \: 2x = 166 - 8$

$\sf\implies \: 2x = 158$

$\sf \implies \: x = \cancel \dfrac{158}{2}$

$\sf \implies \: x = 79$

One number = x = 79

Another number = x + 8 = 79 + 8 = 87

3 + 4ab+ 4ab - 5b + m

Rainbow [258]

Answers:

Number of terms: 5
Coefficients: 4, 4, -5 and 1
Constant term: 3

===================================================

Explanation:

Each term is separated by a plus sign or a minus sign. We could rewrite the 4ab-5b portion as 4ab + (-5b) to help get everything separated by a plus sign.

The five terms are

The coefficients are the numbers just to the left of the variable. For a term like 4ab, the coefficient is 4. For the term "m", we can think of it as 1m so we can see it has a coefficient of 1.

The constant term is the term that doesn't have any variable attached to it. That would be the "3" as the first term.
