A graph titled Starting Salaries has education (years) on the x-axis and Starting Salary (one-thousand dollars) on the y-axis. A line goes through points (10, 20) and (14, 25).
A researcher surveyed 8 people to see if there is a relationship between years of education and starting salaries. The data points are shown on the graph.

Which best represents the equation of the trend line shown on the graph? (Note that the graph has a break on the x-axis.)

y = 0.25x + 15
y = 0.25x + 17.5
y = 1.25x – 10
y = 1.25x + 7.5

What is the similarity ratio of a cube with volume 729m^3 to a cube with volume 3375 m^3

Write the equation of a line that is perpendicular to the given line and that passes through the given point. –3x – 6y = 17; (6, 3) y = x – 9 y = 2x – 9 y = –2x – 9 y = x + 0 3. is the relationship shown by the data linear? if so, model the data with an equation. x y 1 5 5 10 9 15 13 20 the relationship is linear; y – 5 = (x – 1). the relationship is not linear. the relationship is linear; y – 5 = (x – 1). the relationship is linear; y – 1 = (x – 5). write an equation in point-slope form for the line through the given point with the given slope. (–10, –1); m = y + 10 = (x + 1) y – 1 = (x – 10) y – 1 = (x + 10) y + 1 = (x + 10) 5. write an equation for each translation of . 6.5 units up y + 6.5 = | x | y = | 6.5 x | y = | x | + 6.5 y = | x | – 6.5 6. write an equation for each translation of . 5.5 units right y = | x | + 5.5 y = | x – 5.5 | y = | x | – 5.5 y = | x + 5.5 | 7. which equation translates y = | x | by 8 units to the left? y = | x | – 8 y = | x | + 8 y = | x – 8| y = | x + 8|
