Answer: 1. A) 2/5 B) X= -5 Y= 2
2. A) -3/2 B) X= 2 Y= 3
3. A) -2/3 B) X= -3 Y= -2
Step-by-step explanation: A) Look where the line intersects perfectly through a corner of one of the boxes, find the next one closes to that count how many it goes up and how many across. Rise/Run so the amount it goes up goes on the top of the fraction and the amount across on the bottom of the fraction.
B) This is where the line intersects the X and Y axis
Answer:
The difference between 5 and a number x, is that 5 is a constant number no matter what, while x can be considered as any real number.
Answer:
-1/4 is the slope and the y intercept is -4
Step-by-step explanation:
Solve for y
x +4y = -16
Subtract x
4y = -x-16
Divide by 4
4y/4 = -x/4 -16/4
y = -1/4 x -4
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
-1/4 is the slope and the y intercept is -4

Hi!
50) The answer is 104 cm
Steps:
-recognize that the shape is a triangle and a rectangle put together
-find the measurements of the triangle (8&6) and the rectangle (8&10)
-find the areas of the triangle (l x h divided by 2= a) and the rectangle (l x h+a)
-add the areas together (24& 80)
51) The answer is 800ft
Steps:
-split the irregular shape into a triangle and a rectangle
-find the area of both the triangle (200) and of the rectangle (600)
-add together (200+600= 800)
52) The answer is 156 cm
Steps:
-recognize that the shape can be split into 3 rectangles
-find the measurements for all three rectangles (12&5, 12&6, 3&8)
-Use the formula l x h= a for each rectangle
-add each one of the rectangles together (60, 72, &24)
