Answer:
Dot plot
Step-by-step explanation:
In a dot plot, the temperature of a day is represented by 1 dot. There are 30 dots on the box plot shown in the attachment that was made by Tia.
This dot plot display makes it easier to find how many days had a temperature that is higher than 15°.
Thus, from the dot plot, we have:
2 dots representing 2 days having a temperature of 16°C each
2 days also have daily temperature of 17°C
2 days have temperature of 18°C as well, and
1 day has temperature of 19° C.
Therefore, the number of days that had a temperature above 15°C is 7 days.
11) 7 + -10+(4(5+-3)) = 7+-10+8=5
12) (12 +-10)+3x+-1(2x+4x), 12+-10x+3x+-2x+-4x = 12+-13x

Answer: B.
Step-by-step explanation: A triangle is 180 degrees. m< a + b + c = 180, so 75+20+x=180, so x = 85. B.
Answer:
Step-by-step explanation:
From the given information, we already know two points the line intersects. It states that the line has a y-intercept of 3. The y-intercept is the point at which the line intersects the y-axis. Thus, the line also intersects (0,3). (Remember that all points on the y-axis have an x-value of 0.) Now we have enough information to write an equation.
1) Find the slope of the line with the slope formula, 
. Substitute the x and y values of (-5,2) and (0,3) into the formula and solve:
So, the slope of the line is 
.
2) Now we can write the equation in slope-intercept form, represented by the formula 
. Substitute values for 
and 
in the formula.
The represents the slope, so substitute for it. The represents the y-intercept, so substitute 
for it. This gives the following answer and equation in slope-intercept form:
