The answer would be C. The line is best fit so the Y-intercept wouldn't show EXACTLY how much it would cost, just around how much it would cost. (Approximately)
Tems11 [23]4 years ago

Answer:

The line of best fit is the line , which describes the relationship between x and y coordinate in two dimensional plane.The line may pass through a single point, all the points or none of the points.

The equation of line in slope intercept form is

y=m x +c

c=Y-Intercept

Also, Y-Intercept = 965

So, Equation of line is , y= m x + 965

X axis =Number of blocks from city center

Y axis=Property price (In thousand dollars)

m=Slope made by positive direction of X axis,which is 90°<tan(theta)<180°, will be negative.

If you substitute , x=0,then we get , y= 965 dollars.

Also , for x=1,2,3,..the price of property decreases by certain amount but not by value of 965.

So, option

(B) and (C)  A property that is 0 blocks from the city center can be expected to cost approximately $965,000. is surely true.

Which of these triangle pairs can be mapped to each other using two reflections? Triangles X Y Z and P Y T are connected at poin
Irina18 [472]

Answer:

The correct option is the first option;

Triangle XYZ and PYT are connected at point Y. Triangle XYZ is reflected across XY and then is reflected another time across YZ to form triangle PYT

Step-by-step explanation:

To answer the question we look at each option as follows;

1) The parameters given are triangle XYZ and PYT are connected at point Y

Triangle XY is reflected about XY will shift the marked angle from left to right while the right angle will remain at the same location and the triangle will remain upright to give triangle X'Y'Z'

Reflection about the YZ will give; the marked angle and the right angle in the same location and the vertex X will then be changed to P

Therefore, triangle XYZ can be mapped to triangle PYT with two reflections

2)  In the second option, we have triangle XYZ is reflected 3 times which is more than 2 times as in the question, therefore, option two is less suited as an answer to the question

3) Triangle XYZ is reflected across side XY and then is shifted down to form triangle AYT

Therefore, since we have only one reflection, option 3 is also not appropriate as an answer

4) In option 4 triangle XYZ is reflected and then rotated therefore option 4 is also not a correct option.

Write the equation of a line, in slope-intercept form, that has a slope of m=9 and passes through the point (4, 31)
Darina [25.2K]

Answer:

9x-y = 5

Step-by-step explanation:

Equation of line in slope intercept form:

y-y1 = m*(x-x1), m=9, (x1,y1)=(4,31)

y-31 = 9*(x-4)

y-31 = 9x-36

9x-y = 36-31

9x-y = 5
