Write an equation that passes through the points (0,-5) and (8,-5)

bezimeni [28]

Answer:

Equation of the line: $y = -5$ .

Step-by-step explanation:

Let $(x_0,\, y_0)$ and $(x_1,\, y_1)$ denote the coordinates of these two points, respectively.

Calculate the slope $m$ of this line:

$\displaystyle m = \frac{y_1 - y_0}{x_1 - x_0} = \frac{(-5) - (-5)}{8 - 0} = 0$ .

Notice that the slope is zero because the two points have the same $y$ -coordinates ( $y_0 = y_1 = -5$ ) even though their $x$ -coordinates are distinct ( $x_0 \ne x_1$ .)

Equation for this line in point-slope form:

$y - y_0 = m\, (x - x_0)$ .

$y - (-5) = 0\, (x - 0)$ .

Rewrite and simplify to obtain the equation of this line in slope-intercept form:

$y = -5$ .

The $x$ -term was eliminated because the slope was zero.

Which phrase describes the algebraic expression 6x?

topjm [15]

Answer:

The product of 6 and a number

Step-by-step explanation:

There isn't any "real" mathematics needed to find the answer, just common background knowledge:

6x = 6 times x,

and product is referencing multiplication

(Since quotient is for division, difference for subtraction, and sum for addition)

considering we need to represent an expression which uses multiplication in words, the correct answer is:

O the product of 6 and a number
