Answer:

Step-by-step explanation:
Find the slope using the points, (1, -3) and (3, 1):

m = 2
Find the y-intercept (b) by substituting x = 1, y = -3, and m = 2 in 


Subtract 2 from both sides



Plug in the value of m and b into the slope-intercept form equation,
.
Thus:

✅
surface area= perimeter x height + 2b
s= pxh+2b
example: 18(8)+2(12)
explain: 18 is the perimeter and 8 is the height then you have to add the base times 2
Answer:
C
Step-by-step explanation:
This one is quite easy. If you look angle M is slightly obtuse which means that it can't be A or B but it is to small to be D.
Right Triangles and the Pythagorean Theorem
The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
The side opposite the right angle is called the hypotenuse (side c in the figure).
