The table represents a linear equation.

y – 8 = –0.15(x – 10)

y + 8 = –0.15(x – 10)

y – 8 = –0.2(x + 10)

y + 8 = –0.2(x – 10)

The slope-intercept form of the equation of a line that passes through point (–2, –13) is y = 5x – 3. What is the point-slope form of the equation for this line?

y – 13 = 5(x – 2)

y + 13 = 5(x + 2)

y – 2 = 5(x – 13)

y + 2 = 5(x + 13)

Marty and Ethan both wrote a function, but in different ways.Marty Ethan

The total cost for a bucket of popcorn and 4 movie tickets is $56. The total cost for the same size bucket of popcorn and 6 movie tickets is $80. The cost of a bucket of popcorn is $8. Which equation represents the relationship between y, the total cost of the popcorn and movie tickets, and x, the number of movie tickets that are purchased?

y = 12x + 8

y = 12x − 8

y = 14x + 8

y = 14x − 8

Line AB passes through points A(−6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y=mx+b, then m=. What is the value of b?

−6

−5

Line CD passes through points (0, 2) and (4, 6). Which equation represents line CD?

y = 2x – 2

y = 2x + 2

y = x + 2

y = x – 2

The point-slope form of the equation of the line that passes through (–5, –1) and (10, –7) is . What is the standard form of the equation for this line?

2x – 5y = –15

2x – 5y = –17

2x + 5y = –15

2x + 5y = –17

Line CD passes through points C(1, 3) and D(4, –3). If the equation of the line is written in slope-intercept form, y = mx + b, what is the value of b?

–5

–2

The point-slope form of the equation of the line that passes through (–4, –3) and (12, 1) is y – 1 = (x – 12). What is the standard form of the equation for this line?
