Find the equation of the line that passes through the points (1, 6) and (2, 8).
By substitution in this equation, show that (3, 10) also lies on this line.

Answers

Answer:

y = 2x + 4

Step-by-step explanation:

y2 - y1/ x2- x1  

= 8 - 6 / 2 - 1

= 2

So now our equation is y = 2x + b (from y = mx+b). Now plug in the coordinates to find the y-intercept.

y = 2x + b

8 = 2(2) + b

8 = 4 + b

4 = b

The y-intercept is 4.

If we put one of the values like the x in the equation, we should get the y value.

y = 2x + 4

y = 2 (3) + 4

y = 6 + 4

y = 10

Answer:

5x + 5x = 10x

Combine like terms: 5x + 5x = 10x

10x = 10x

Add '-10x' to each side of the equation.

10x + -10x = 10x + -10x

Combine like terms: 10x + -10x = 0

0 = 10x + -10x

Combine like terms: 10x + -10x = 0

0 = 0

Step-by-step explanation:

Answer: 5x+5x=10x²

10x=10x²

10x²+ -10x²=0

10x+-10x²=0

10x(1+ -1x)=0

Lead-the-market pay strategies. An employer may choose to establish an internal compensation strategy that is in excess of the pay rates in the prevailing marketplace. This compensation strategy may increase the supply of candidates, increase selection rates of qualified acpplicants, decrease employee turnover, increase morale and productivity, or prevent unionization efforts. However, prior to implementing a lead compensation strategy, an organization should carefully consider what benefits it expects to realize from such a strategy, keeping in mind that this type of structure has the greatest propensity of increasing overall labor costs.
