Answer:
You have it y=-1
Step-by-step explanation:
It's hard to explain
(3,5)....x1 = 3 and y1 = 5
(1,3)....x2 = 1 and y2 = 3
slope formula : (y2 - y1) / (x2 - x1)
slope = (3 - 5) / (1 - 3) = -2/-2 = 1 <== slope is 1
Answer:
S= 5, L= 12
Step-by-step explanation:
To find the value of L and S, we need to first label the 2 equations.
L +S= 17 -----(1)
3L +2S= 46 -----(2)
From (1):
L= 17 -S -----(3) <em>(</em><em>-S</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
Subst. (3) into (2):
3(17-S) +2S= 46
3(17) -3S +2S= 46 <em> </em><em>(</em><em>expand</em><em>)</em>
51 -S= 46
-S= 46 -51 <em>(</em><em>-51</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
-S= -5
S= 5 <em>(</em><em>divide</em><em> </em><em>by</em><em> </em><em>-1</em><em> </em><em>throughout</em><em>)</em>
Subst. S=5 into (3):
L= 17 -5
L= 12
