How to determine whether two known pairs of points are on the same line.

Find an equation of the line perpendicular to the graph of 28x-7y=9 that passes through the point at (4,1)

M the table below represents a linear function f(x) and the equation represents a function g(x): x f(x)−1 −50 −11 3g(x)g(x) = 2x − 7part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)part b: which function has a greater y-intercept? justify your answer. (4 points)
