An equation for the ellipse ( standard form ):
x²/a² + y²/b² = 1
Here is: a - semi-major axis and b - semi-minor axis.
Radius of the moon is 1,000 km and the distance from the surface of the moon to the satellite varies from 953 km to 466 km.
a = 1,000 + 953 = 1,953 km
b = 1,000 + 466 = 1,466 km
Answer:
The equation is x² / 1,953² + y² / 1,466² = 1
or: x²/3,814,209 + y²/2,149,156 = 1

Answer:
(0,-121/7)
Step-by-step explanation:
11x-7y=121
11(0)-7y=121
-7y=121
y=121÷-7
0'-121/7
Answer:
Slope = 2/3
intercept= 1/3
Step-by-step explanation:
The standard form of equation of a line in slope intercept form is expressed as;
y = mx+b
m is the slope
b is the y-intercept
Given the expression
y-3=2/3(x-4)
Cross multiply
3(y-3)=2(x-4)
Expand
3y - 9 = 2x - 8
3y - 2x = -8 + 9
3y - 2x = 1
3y = 2x+1
Divide through by 4
y = 2/3 x + 1/3
Comparing
mx = 2/3 x
m = 2/3
b = 1/3
Hence the slope of the function is 2/3 and the intercept is 1/3
