Consider three points in the plane, P(-1,0), Q(1,1) and R(2,3). Part A: Find the equation of the line through P and Q.
Part B: Find the equation of the line that is parallel to line PR and is passing through the point Q
Part C: Find the equation of the line that is perpendicular to line QR and is passing through point P

For the given quadratic equation convert into vertex form, find the vertex and find the value for x=6 y=-2x^2+2x+2

Thompson and thompson is a steel bolts manufacturing company. their current steel bolts have a mean diameter of 127 millimeters, and a variance of 36. if a random sample of 35 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by greater than 0.5 millimeters? round your answer to four decimal places.

Solve for x and y a x= 13.3 y= 16.7 b x= 23.3 y= 12.5 c x= 7.5 y= 16.7 d x=7.5 y= 12.5
