Find five solutions to the linear equation x + y = 6

x / x + y = 6 / y

Based on the graph, does the point 173, 13 belong to the graph of the linear equation

x + y = 6?

Just by looking at the graph, would you say that -237, 4 is a point on the graph of

x + y = 6?

Predict what shape this linear equation will be:

Review:

2. / Eman walks from the store to her friend’s house, 2 miles away. It takes her 35 minutes. What is her constant speed, C?
Use a proportion to determine how many miles she walks after 10 minutes. Round your answer to the hundredths place.
Write a two-variable equation to represent how many miles Eman can walk over any time interval.
3. / Simplify: 8(-3)(5) ÷ 5
