Every Monday for the first three Mondays of November it has rained. If you were to make a prediction that it will rain the last Monday of the month, are you using inductive or deductive reasoning?

Inductive; you are using a pattern of observations to make a conclusion

300

What is the hypothesis of the following statement?

Equations of lines

100

Identify the slope of the line:

y= 3x + 5

m = 3

200

y=2/5x+7

400

Write the general form of point-slope form.

y-y₁=m(x-x₁)

500

Write an equation of the line that passes through the point (5, 9) and (1, -3)

y = 3x - 6
