Answer: (c) The slope is 9, and the y-intercept is -2.

Explanation:

The general slope intercept form of a linear function is as follows:

y = mx + b

where m is the slope and b is the y-intercept. The value m determines steepness and orientation of the line, and value b the vertical shift of the line.

By comparison to the general form we can identify:

the slope (m) is 9

the y-intercept (b) is -2.

Choice (c) reflects correctly this situation.

Sari drives 55 miles per hour. Which equation shows the proportional relationship between hours (h) and miles (m)?

Finger [1]

Answer:

$m=55h$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

m ----> the distance in miles (y-coordinate)

h ----> the time in hours (x-coordinate)

In this problem the constant of proportionality k is given and is equal to

$k=55\ \frac{miles}{hour}$ ----> the speed

substitute

$m=55h$

What is the equation of the horizontal line that passes through the point (-2, -1)

diamong [38]

Answer:

y= -1

Step-by-step explanation:

A horizontal line would mean that it has no slope, since the line is not decreasing or increasing. The horizontal line drawn through (0, -1) would pass through (-2, -1), since they share the same y coordinate.
