Answer: y=2x-1
Step-by-step explanation:
Equation of a line that passes through (a,b) and have slope m is given by :-
[point slope form]
Given, Point = (4,7) , m= 2
Equation in point slope form : 
To write in slope intercept form (y=mx+c) , we need to simplify it

Hence, y=2x-1
Answer:
16 rolls of ribon
Step-by-step explanation:
C = Dπ
d = r x 2
d = 100 x 2
d = 200
C = 200 x 3.14
C = 628
628 / 40 = 15.7
she should buy 16 rolls
Let a,b,c be the sides of the triangle. Make c the longest side. The value of a and b doesn't matter.
a = 9
b = 40
c = 41
The value of a^2+b^2 is
a^2+b^2 = 9^2+40^2 = 1681
The value of c^2 is
c^2 = 41^2 = 1681
Because a^2+b^2 = c^2 for these values, this means that we have a right triangle.
Answer is choice D
