Answer:

Step-by-step explanation:
slope (rise over run) choose 2 points that are easy to figure out. Count up and over to get the slope
(0,3) and (4,4)
3 to 4 is 1
0 to 4 is 4
slope is 1/4
y intercept is b- so +3
y=
You will use the polygon sun theorem.
(N-2)(180)
Plug in you're number for N
(37-2)(180)
Can you figure out how to solve the rest of the problem?
Answer:
x=24cm
y=20,78cm
Step-by-step explanation:
sen(30)=
-> x*sen(30)=12 -> x=
= 24cm
cos(30)=y/x -> cos(30)= y/24 -> y=24*cos(30)= 20,78cm
Answer:
x - y = 0
Step-by-step explanation:
General form of equation of straight line is
ax + by = c
that is we have to keep terms containing x and y on LHS and term independent of x and y on RHS.
given
x = y
there, no term independent of x and y
now we have to bring y one RHS
for that we subtract y from LHS and RHS
x - y = y -y
=> x - y = 0
Thus, option x - y = 0 is the correct answer.
Plug this into the formula y2 - y1 / x2 - x1
-2 = x1, x2 = 2, y1 = -1, y2 = -3
-3 - (-1) / 2 - (-2)
-2 / 4
-1/2
The slope is -1/2.
