Question

write an equation in point-point form for the line through the given point with the givedescribe how the graph of y | x| -4 is like the graph of y= |x| and how it is different. slope. (-3,-7); m=-6/5

Answer 1

a) The point-slope form of the equation of a line through point (h, k) with slope m is
y - k = m(x - h)

In point-slope form, the equation of the line through (-3, -7) with slope -6/5 is
y + 7 = (-6/5)(x + 3)


b) The graph of
y = |x|-4
represents a translation downward 4 units of the graph of
y = |x|
It retains the same general shape and axis of symmetry, but will have two (2) x-intercepts instead of one (1).
