Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Slope-Intercept Form: y = mx + b

m - slope
b - y-intercept

Step-by-step explanation:

Step 1: Define

Find points from graph.

y-intercept (0, -2)

Random Point (2, 1)

Step 2: Find slope m

Substitute [slope formula]: $m=\frac{1+2}{2-0}$
Add/Subtract: $m=\frac{3}{2}$

Step 3: Write equation

Substitute into General Form

y = 3/2x - 2

What is the best estimate of 28 × 4,417?

Maru [420]

Answer:

132600

Step-by-step explanation:

I was always taught like this, and this should be the best estimate:

28 x 4417 --> 30 * 4420 --> 132600

Some other possible estimates with simpler values:

30 * 4400 --> 132000

30 * 4500 --> 135000

30 * 4000 --> 120000

What is the slope of the line joining (8,8) and (12, 6)?

Anna71 [15]

Answer:

$\huge \boxed{ \boxed{ - \frac{1}{2} }}$

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

From the question we have

$m = \frac{6 - 8}{12 - 8} = - \frac{2}{4} = - \frac{1}{2} \\$

We have the final answer as

$- \frac{1}{2} \\$

Hope this helps you
