Slope intercept form is this: y - y1 = m(x - x1) We are given the point of (5, -4) and the equation y = 2x + 3 Our needed equation is parallel to the give equation, meaning it has the same slope which is 2 Plug in the slope which is 2x and the x1 and y1 values given.
y - (-4) = 2(x - 5)
Then, simplify the equation to receive our answer. y + 4 = 2x -10 y = 2x - 14
Mr. Luna's travels east and west are irrelevant to the question. He drives 3 miles north, then he drives 4 more miles north. 3 + 4 = 7, so Mr. Luna ends up 7 miles north of his home.
Domain of fg(x) is determined by the domain of g(x).g(x) has domain such that x is any real number.So domain fg(x) is x such that x is any real number.
