Step-by-step explanation: Because ....
Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1) .... x_1 = 3 and y_1 = - 1
m is the slope to x - 3y = 9 because (lines are parallel )
calculate : m by equation x - 3y = 9 :
x = 3y +9
divid by : 3 1/3 x = y + 3
y = (1/3) x - 3 so : m = 1/3
an equation parallel to x - 3y = 9 that passes through the point ( 3, -1 ) is :
y +1 = (1/3)(x - 3)
Answer:
b. Is because -3 because the the negative gets turned into a positive.
5. They are almost the same because subtraction change the negative to a positive and the -5+2 is the aftermath of what happend.
6. Its because the subtract a negative it cancels out and makes the number a positive.
