Answer:
Step-by-step explanation:
Because 
and its inverse, 
, give a sum of 0, this shows the identity property of 0.

128
Step-by-step explanation:
First find the slope of this new line; it's the same as the slope of the "given line," which you unfortunately have not yet given. Let's call that slope "m."
Then, the equation in point-slope form of the new line is
y - (-1) = m(x - [-1]), or y+1 = m(x+1)
Please go back to the original question, obtain the slope of the "given line," and substitute that value for m in y+1 = m(x+1).
1) The y- axis is where x = 0, so the line "y = -1/2x - 3" will cross the y-axis when x = 0. You plug in "x = 0" into the equation, and get y = 0 -3, so y = -3. That means the line " y = -1/2x - 3" will cross the y-axis ar (0, -3)
2) If there are 2 parallel lines, then there is no solution, because the definition of parallel lines is, " 2 lines in the same plane, that never meet." That makes the solution inconsistent.
Y = 4/-3 - 1
The slope can either be -4/3 or 4/-3 and the y-intercept is (0,1)
