What is equation of a line with slope of 3 that goes through the point of (7,-1)

y = 3x - 22

Step-by-step explanation:

y = mx + b

plug in slope

y = (3)x + b

plug in (x, y)

-1 = 3(7) + b

multiply

-1 = 21 + b

subtract

-22 = b

plug in b

y = 3x - 22

Step-by-step explanation:

y = mx + b

m = 3   ⇒   y = 3x + b

The line goes through P so:  

-1 = 3(7) + b

-1 = 21 + b

b = -22

y = 3x - 22

3x - y = 22              

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
