Change the equation to slope intercept form: y= mx + b. m is slope and b is the y-intercept.
7x+4y=10
subtract 7x
4y=10-7x
divide by 4
y=(10-7x)/4
y=10/4-7x/4
simplify
y=5/2-7x/4
swap positions for correct form
y= -7/4x + 5/2
slope= -7/4
Answer:
Step-by-step explanation:
T(x , y) = (-x -y, -x +y)
T(1, 0) = (-1, -1) = -1(1 , 0) -1(0 , 1)
T(0, 1) = (-1, 1) = -1(1 , 0) +1(0 , 1)
Therefore,
|T| = [-1 -1] = -2
T is invertible
Therefore,
