Answer:
1/3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-4-(-5))/(3-0)
m=(-4+5)/3
m=1/3
just write the expression
if its for math but then i dont know
60
n = 20
d = 6
a = 4
L = a + (n - 1)*d
L = 4 + (20 - 1)*6
L = 4 + 19*6
L = 118
Sum = (a + L)*n/2
Sum = (4 + 118) * 20/2
Sum = 122 * 10
Sum = 1220
its the second one -3(x-y)
