Answer:
System of Linear Equations entered :
[1] 4x - 3y = 15
[2] 2x + 2y = 4
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -2x + 4
[2] y = -x + 2
// Plug this in for variable y in equation [1]
[1] 4x - 3•(-x +2) = 15
[1] 7x = 21
// Solve equation [1] for the variable x
[1] 7x = 21
[1] x = 3
// By now we know this much :
x = 3
y = -x+2
// Use the x value to solve for y
y = -(3)+2 = -1
Solution :
{x,y} = {3,-1}
Answer:
6/7
Step-by-step explanation:
Given the points :
(-5, 2) and (2, 8)
Slope can be obtained by using the relation :
(y2 - y1) / (x2 - x1)
From the points given :
x1 = - 5 ; y1 = 2 ; x2 = 2 ; y2 = 8
(8 - 2) / (2 - (-5))
(8 - 2) / (2 + 5)
6 / 7
Hence, slope between the two points = 6/7
