Question: The variables x and y are directly proportional, and y = 4 whenx = 3. What is the value of y whenx = 15?

Which equation represents the line that passes through the points and (4, 10) and (2, 7)? y = 3/2x - 11y = 3/2x +4y = - 3/2x + 19y = - 3/2x + 16

Lindsay used two points, (x,y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?

What is the effect on the graph of the function f(x)=x when f(x) is replaced with -f(x)+4
