)The equation of the line of best fit of a scatter plot is y = −4x − 6. What is the the y-intercept?
Gekata [30.6K]
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

A shop owner can buy two televisions and three DVD players for $1750 or four televisions and one DVD players for $1250. Find the
Alenkasestr [34]

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
