Find the slope of a line that passes through (-2,1) and (4,9)
melamori03 [73]

Answer:

m = 4/3

Step-by-step explanation:

To find the slope of a line use the formula, where "m" means slope:

m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }

*You don't need to show this part on paper*

Choose which point you want to be point 1 and point 2. Remember the points are written (x, y).

Point 1: (-2, 1)       x₁ = -2  y₁ = 1

Point 2: (4, 9)      x₂ = 4   y₂ = 9

Substitute the coordinates into the formula:

*Show this part on paper*

m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }

m=\frac{9-1 }{4-(-2) }         Simplify

m=\frac{8 }{6 }                Reduce by dividing by 2

m=\frac{4 }{3 }               Slope

The slope of the line is 4/3

Xerxes is selling cups of lemonade. He is selling regular and pink lemonade in 3 sizes: small, medium, and large. The table disp
raketka [301]

Part 1

Add up the values in the table: 90+36+54+45+63+72 = 360

This means 360 total drinks were sold. Of that total, 54 were medium regular.

The percentage of medium regular is 54/360 = 0.15 = 15%

Apply this percentage to the 640 customers he plans to sell to

15% of 640 = 0.15*640 = 96

<h3>Answer: 96</h3>

============================================

Part 2

It sounds like your teacher wants you to find the probability of picking pink lemonade. The table says that 36 small, 45 medium, and 72 large pink lemonades were sold. That means 36+45+72 = 153 pink lemonades were sold out of the 360 total

153/360 = 0.425

Then go through each answer choice to note that 17/40 = 0.425 as well

Therefore, 153/360 = 17/40

Answer: 17/40
