Chapter 4.2, Problem 20E

Find the coefficient of the straight line equation (a and b) in the equation Y = aX + b from the following data (in the table)

The graph of the line y=1/3x+1 intersects a second line at a right angle . If the y intersect of the second line is( 0,11) what is the point at which the lines intersect. A.(15,6) B.(-3.6,-(0,2) C.(3,2) D. (-3.75,-0.25)

Consider the lines normal to the curve 3x2 - y2 = 8 that are parallel to line x + 3y =4. Let A be the sum of x - coordinate (s) of the point(s) of normalcy. Let B the mean y - coordinate(s) of the point normalcy refers to the point on the graph where a line in perpendicular to the curve. The sum A + B is equal to ________
