Why do we reverse the direction of the inequality symbol when multiplying or dividing by a negative number?

1 answer:

7 0

When you multiplied both sides by a NEGATIVE number, what WAS negative became positive, and what WAS positive became negative! Everything that was larger became small, and what was smaller became large. Everything REVERSED

Making and Interpreting Correlations: Mastery Test

garri49 [273]

Answer:

Graph D > Graph A > Graph C > Graph B

Step-by-step explanation:

The closer the data points are to each other along the line of best fit, the greater the value of their correlation coefficient, and vice versa.

Therefore, the graphs can be arranged in descending other (from the highest to the lowest) based on the values of their correlation coefficients as follows:

Graph D > Graph A > Graph C > Graph B

Write the equation in slope-intercept form of the line that has a slope of 2 and contains

mina [271]

Equation in slope-intercept form is y = 2x - 6

Step-by-step explanation:

Step 1: Given slope of the line, m = 2. Form an equation y = mx + b

⇒ y = 2x + b ---- (1)

Step 2: The line passes through the point (4,2). So it will satisfy the equation. Find b by substituting x = 4 and y = 2.

⇒ 2 = 2 × 4 + b = 8 + b

⇒ b = -6

Step 3: Form the slope-intercept equation.

⇒ y = 2x - 6
