Find the slope and y-intercept for the two linear functions. Linear Functions Identify the slope of the line given in the table:

Natalija [7]

ANSWER

See explanation

EXPLANATION

The table contains these two points (-4,-3) and (2,-4.5)

The slope of this line is given by;

$m = \frac{rise}{run}$

$m = \frac{ - 4.5 - - 3}{2 - - 4} = \frac{ - 1.5}{6}$

$m = - \frac{1}{4}$

The y-intercept can be obtained by finding the equation of the line in the form:

$y = mx + c$

We plug in the slope and the point (-4,-3) to find c.

This implies that,

$- 3 = - \frac{1}{4} \times - 4 + c$

$- 3 = 1 + c$

$c = - 3 - 1 = - 4$

Hence the y-intercept is -4.

The given line is

$y = \frac{3}{2} x + 1$

This is already in the slope intercept form:

The slope is

$m = \frac{3}{2}$

The y-intercept is c=1

Which rule represents Ro, 180º?

Ksju [112]

Answer: (x, y) = (-x, -y)

Step-by-step explanation:

To solve this, you can match the coordinates of points on the triangles and choose the correct answer from there.

The highest point on the triangle, S, has coordinates of (3, 5).

The reflected triangle's point S has coordinates of (-3, -5).

Point Q on the triangle has coordinates of (1, 0)

Point Q on the reflected triangle has coordinates of (-1, 0).

Matching these two points and their reflections to the answers, the only answer that fulfills both points correctly is (x, y) = (-x, -y).
