Do Now:
1) If a car travels at a constant speed of 30 miles per
hour, how long will it take to travel 96 miles.
2) Zeb is 5 years older than Yolanda. The sum of
their ages is 41. How old are they?
For #'s 1 and 2 (put in slope intercept, y=mx+b)
m=slope
b=y-intercept
Parallel Lines = Same slope
Perpendicular = negative reciprocal slope
Neither = Different slopes but not negative reciprocals
For #'s 3 and 4 (put in slope intercept, y=mx+b)
Same Slope, Different y-intercept = Parallel (0 Solutions)
Same Slope, Same y-intercept = Same Line (Infinite Solutions)
Different Slope = Intersect (1 Solution)
For #'s 5 and 6
Put in y=mx+b and graph both lines, where they cross is the
solution.
For #'s 7 and 8
Plug in the values - If you get yes twice then it is YES
If you get no ever then it is NO
