The table shows the number of tickets sold for a concert when different prices are charged. write an equation of a line of fit for the data. round all values to the nearest tenth.
y=
x+
question 2
does it seem reasonable to use your model to predict the number of tickets sold when the ticket price is $85? explain.
yes; predictions can always be made using a line of fit.
yes; the data show a strong negative correlation for the line of fit.
no; the value 85 is not close to the values used to create the line of fit.
no; predictions can only be made for values used to create the line of fit.

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.

Are the corresponding angles congruent? explain why or why not.
