If two lines are perpendicular, then their slopes have a product of -1 or you could say they are opposite signed reciprocals of each other.
The given equation has a slope of -3. We know this because it is in slope-intercept form y = mx + b ...y = (slope)x + (y-intercept).
so taking the slope -3...the opposite signed reciprocal would be +

Now we have a slope and a point... we can use them to find the b (y-intercept)
x = 4, y = 3, and m =



Using the common denominator fraction for 3, we subtract 4/3 from both sides


plug the values for m and b into the slope intercept form

last one
Step-by-step explanation:
Step-by-step explanation:
its say $3.50 each so for a week you multiply $3.50 by 3 because the are 3 days which will be equal to $10.5
the you divide $84 by $10.5
and the answer is =8weeks
Answer:
6×250=(3×2)×250
Step-by-step explanation:
You would 6/3
which wIll give you 2
For a triangle to be right angled the largest side squared must equal the sum of the squares on the other 2 sides ( Pythagoras theorem)
1. 101^2 = 99^2 + 20^2 so its is right angled
2. 28^2 is not equal to 26^2 + 12^2 - not right angled
3. 17^2 not euql to 14^2 + 6^2 - not
