Step-by-step explanation:
<h3>Equation of the line in slope- intercept form:</h3>
Here, m is the slope and b is the y-intercept
Find the slope with the given two points.
Slope = -2/3 and choose any one the given points.
Substitute m = -2/3 and (5,6) in the above equation and find 'b'
Equation of the line:
Answer:
The sister is 10 and Mike is 20
Step-by-step explanation:
10 x 2 = 20
10 +20 = 30
Let's rearrange the terms to convert the equation into slope - intercept form ~

Answer:
-2, -6
Step-by-step explanation:
using cramer rule
5 -3
-2 -1
calculatiing the determinant = (5 x-1) - (-3x-2) = -5 -(6) = -5-6=-11
using cramer rule
to calculate x we change the coefficient of x with the answer (8,10)
8 -3
10 -1
we calculate determinant = (8x-1)-(-3x10) = -8-(-30) = -8+30 =22
to calculate x
22/-11= -2
to calculate y we change the coefficient of y with the answer (8,10)
5 8
-2 10
we calculate determinant = (5x10)-(8x-2) = 50 -(-16) = 50 +16=66
to calculate y
66/-11= -6
