Y = mx + b, where m = slope, and b = y-intercept.
Since you are not given the y-intercept, you have to solve for it through the equation, y = -3x (which is the slope you are given) + b, and replace x and y with values given, which are (1,4)
y = -3x + b
4 = -3(1) + b
4 = -3 + b
7 = b
Then replace b in the first equation to get the answer
y = -3x + 7
Plug in slope and the points in y-y1=m(x-x1)
y-3=2(x-1)
Answer:
540
Step-by-step explanation:
No matter what the shape, the total amount of degrees in the interior angles in a pentagon is 540. Hope this helps!
So you would use the law of sines so set up the equation sin18/16 = sin72/x (sin 72 being the top angle) and then you cross multiply and solve from there:)
Hope this helps!
