The function would do 3 things
1. flip horizontally, because of the negative applied to the slope
2. widen, because of a fractional slope between -1 and 0 (-2/7 makes the rise shorter than the run, so the function widens by going 7 units out for every 2 units down)
3. shift down 7 units, because the initial y-intercept would be changed from, say, 8 to 1. this would bring the graph downwards by 7 units

Answer:
x = -3+√5, -3-√5 (exact roots)
or x = -0.76, -5.24 to the nearest hundredth.
Step-by-step explanation:
x² + 6x = - 4
Completing the square:
(x + 3)^2 - 9 = -4
(x + 3)^2 = 5
x + 3 = +/-√5
x = - 3 + √5, - 3 - √5
Your answer is x = 3.
-3(x + 5) = 6 - 3(2x + 4)
-3x - 15 = 6 -6x - 12
-3x - 15 = -6 - 6x
-3x + 6x = -6 + 15
3x = -6 + 15
3x = 9
x = 3
