Well the y-intercept is where a line crosses the y-axis
y=-4x-6
think of it as y=mx+b
m is always going to be your slope
b is always going to be your y-intercept
y-intercept of y=-4x-6
is -6
1) no

the factors of 12 are 1,2 ,4 , 6,12
the factors of 25 are 1,5,25
the factors of 48 are 1,2,3,4,6,8,12,16,24,48
no because 64 is not a factor of 6 and there will be some of the plastic
miniature dinosaurs left over
the factors of 42 are 1,2,3,6,7,14,21,42

Answer:
Television = $200 and DVD player = $450
Step-by-step explanation:
→ Make 2 equations
Televisions = t and DVD players = d
2t + 3d = 1750
4t + d = 1250
→ Multiply the bottom equation by 3 to make the same variable of d
2t + 3d = 1750
12t + 3d = 3750
→ Minus the two equations to isolate the d variable
-10t = -2000
→ Divide both sides by -10 to find the cost of one television
t = 200
→ Substitute t = 200 back into 4t + d = 1250
800 + d = 1250
→ Minus 800 from both sides to isolate d
d = 450
