Answer:
Y = negative x + 9
Step-by-step explanation:
Find the equation of the line for side S-
m= 4-1/1-4 = 3/-3 = -1
<u>The Gradient is -1</u>
Since parallel lines share the same gradient, it should be either of the first two options.
We can see side Q shares the same gradient: 3-6/6-3= -1
Find the equation of the line of side Q-
y-y1= m(x-x1)
y-6= -1(x-3)
y-6=-x+3
<u>y= -x+9</u>
a
39
-133/-7=19+15=39
check:39-15=19
19x(-7)=-133
125, 216, 343,
no because
29×14 is 406
9×4
20×4
9×1
<u>20×1</u>
49×10 490
490 and 406 aren't equal
