Aline intersects the points (-22, -14) and
(-18, -12). what is the slope-intercept
equation for this line?
y = 4x+

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is

where

m is the slope or unit rate

b is the y-intercept or initial value

step 1

Find the slope

we have the points

(-22, -14) and  (-18, -12)

The formula to calculate the slope between two points is equal to

substitute the values in the formula

simplify

step 2

Find the y-intercept b

we have

substitute

solve for b

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
