The slope intercept equation can be represented as follows:
y = 9 / 7 x + 1
y = 11 / 4 x - 8
y = 11 / 8 x + 6
<h3>How to write slope intercept equation?</h3>
The slope intercept equation can be represented as follows:
y = mx + b
where
Therefore,
The slope intercept equation can be represented as follows:
9x - 7y = - 7
7y = 9x + 7
y = 9 / 7 x + 1
11x - 4y = 32
4y = 11x - 32
y = 11 / 4 x - 8
11x - 8y = -48
8y = 11x + 48
y = 11 / 8 x + 6

B. 1.67
m : n = 2 : 1
( x, y ) = ( (1*3 + 2*(-2))/(2+1) ; (1 * (-1) + 2 * 3) /(2 + 1) ) =
= ( (3-4)/3 ; (-1+6)/3 ) 1.67
Answer: the absolute values and give the answer the same sign
