y = - 7x - 20

the equation of a line in ' slope- intercept form ' is

y = mx + c → (m is the slope and c the y- intercept)

here m = - 7 ⇒ y = - 7x + c

to find c substitute ( - 4 , 8 ) into the equation

8 = 28 + c ⇒ c = 8 - 28 = - 20

y = - 7x - 20 → equation in slope- intercept form

The points (1,2),(1,-3),and (5,-3) form a triangle on the coordinate plane. b. What is the perimeter of the triangle?

Alexeev081 [22]

The perimeter of the triangle is 13.56 units.

The perimeter of a shape on a coordinate plane is found by finding the distance between all points, and then adding them together. It's easier to write it out than to type so I'll attach a photo of my work.
