Answer:
y = 2x - 5
slope = 2
y-intercept = -5
Step-by-step explanation:
You first have to find out the slope.
m = 3 - (-5)/ 4 - 0 = 8/4 = 2
m = 2
slope is 2
y- intercept is -5 because the point (0, -5) crosses the y-axis
you can also find the y-intercept by plugging the slope in for m in the equation y = mx + b.
y = 2x + b
Now we use one of the points to solve for b. I'll use the point (4, 3). Plug in 4 for x and plug in 3 for y.
3 = 2(4) + b
3 = 8 + b
-8 -8
-5 = b
-5 is the y-intercept.

hey it's you again. daniel
Each 90° clockwise turn takes a point (x,y) and transforms it to (y,-x). For a 180° turn you would do this process twice in a row; for a 270° turn, three times in a row.
