The slope-intercept is most usefull
Answer:y = -5x + 11
Step-by-step explanation:
First, find the slope (m) of the line that passes through these points:
m = (1-6) / (2-1) = -5/1 = -5
Then use the point slope formula to find the equation of the line:
m = (y-y0)/(x-x0)
-5 = (y-1)/(x-2)
-5(x-2) = y-1
y - 1 = -5x+10
y = -5x + 11
Well when you add up all three angles of a triangle you should get 180 degrees.
////// The answer is: 4x+2
The answer is B) 20
Because you have 5 brands and you combine each with the 4 others, so 5*4=20
