Question

2. a. graph y = -2 | x - 1 | + 4

Answer 1

since the equation is a linear equation, y = mx+b, we can do this:

find x-intercept by substituting 0 to y and equate for x.
find y-intercept by substituting 0 to x and equate for y.

x-intercept:

0 = -2|x-1|+4
x = 1

so point 1 is (1,0)

y-intercept:

y = -2|0-1|+4
y = 2

so point 2 is (0,2)

now plot the points..
