notice the slope-intercept form, that's the y-coordinate.
Answer:
7. 2|x+2|-1
8. (-2,-1)
10. y≥2
Step-by-step explanation:
7. a|x-h|+k
Vertical stretch by a factor of two, horizontal shift left two, vertical shift down one
8. (h,k)
10. It should be y, but otherwise you are good
remember, you can do anything to an equation as long as you do it to both sides
we can do a subsitution
y=x+6
y=-7x-10
since y=x+6, we can subsitute x+6 for y in the other equation
y=-7x-10
x+6=-7x-10
add 7x to both sides
8x+6=-10
minus 6 from both sides
8x=-16
divide both sides by 8
x=-16/8=-2
the valu eof x that satisfies both equations is x=-2
