Answer:
a) yes, because they both increase by the same increments each time. Tis can be represented by the equation y=5x+2
b) y=5x+2
c) The y-intercept represents the amount of units there were initially and the slope represents the amount of units for every worker.
Answer:
The graph represents a linear function that passes through the origin.
Step-by-step explanation:
Proportional functions can be represented by 
, where 
is some constant. They form a straight line that always pass through the origin (0,0). We can see all these characteristics in the graph, thus the graph is proportional.
Answer:
x=-3 and y=-3
Step-by-step explanation:
add the two equations, so 6x-6x, -6y-3y, and 0+27 to get -9y=27. y ends up equaling -3. plug negative 3 into the either of the equations and solve for x, which ends up being -3
