Developing Equations

Which equation best represents the relationship between x and y in the table shown?

• y= 5x+5

• y=1/5x+5

• y=15x+5

• y=10x+5

In slope intercept form (y=mx+b) what is the "m"?

• The y-intercept

• The x-intercept

• The slope (rate of change)

• A point

In slope intercept form (y=mx+b) what is the "b"?

• The y-intercept

• The x-intercept

• The slope (rate of change)

• A point

What is the y-intercept in the equation?
y = 5x - 4

• 4

For a school assembly, 304 students are to be seated in rows with 16 students in each row. How many rows of students will be seated for the assembly? Let r be the number of rows.

• r = 304 ÷ 16

• r = 16 ⋅ 304

• 304r = 16

• r = 16 ÷ 304

• 16r = 304

Joey and four of his friends went out to eat. They decided to split the bill evenly. Each person paid $11.13. Let b represent the total bill.

• b + 5 = 11.13

• b - 5 = 11.13

• b/5 = 11.13

• 5b = 11.13

A scuba diver dove 16 ft to an elevation of -50 ft. What was her elevation before the dive? Which equation matches the scenario?

• x - 1/6 = 50

• x - 16 = -50

• 1/6 x = 50

• -50 = 16x

If one roll of masking tape costs $1.15, how many rolls can Emma buy with $5.75?

• 1.15(5.75) = x

• 5.75x = 1.15

• 1.15x = 5.75

• x = 1.15/ 5.75

The difference between 5 times a number and 3 is 12.

• 3h - 5 = 12

• 5h - 12 = 3

• 5h - 3 = 12

• 12h - 3 = 3

A number divided by 3 is 10.

• 3n=10

• 3-n=10

• n/3=10
