Answer:
Step-by-step explanation:
58 x 12 = 696 696 + 129 = $825 for a year
they are 9 months in
the first equation is (7,-5.9)
the second equation is (3,10.5)
the third equation is (6,9.4)
the fourth equation is (-5,-4.5)
2x+y=5
y=-2x+5
y-(-2x)=5
y+2x=5
okay
Equation of line: y=3x-18
Point: (4,-6) and slope = 3
y=3x-18
