Can someone help me please

The slope is -2 and the slope-intercept form is y=-2x+20

Step-by-step explanation:

To find the slope between two points, remember to use the equation y2-y1 over x2-x1. That will help you get the slope. To find the y-intercept, use any of the two points given and insert the slope into the equation y=mx+b. For this one I used the two points (7,6)

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
