If you meant to write y=23x-4 then none of the lines are perpendicular.
I suspect you intended y=2/3x-4, then line D, y=-3/2x-4 is perpendicular.
For any line y=mx+b, you have to "invert" m to get a perpendicular line. Inverting in this case means: flip numerator and denominator and add a minus sign.
So 2/3 becomes -3/2, hence answer D.
The 'inverted' m is called the opposite reciprocal. That's your word of the day.
Answer:
The slope is 3 and the line is rising.
Step-by-step explanation:
To find the slope m of a line given two points (x₁, y₁) and (x₂,y₂) we can use the formula:
m = (y₂-y₁) / (x₂ - x₁)
In this problem we have the points (6,2) and (7,5), substituting these values in the formula we get:
m = (5 - 2) / (7 - 6) = 3/1 = 3
Therefore, the slope is 3.
Given that the slope is positive we can conclude that the line through the points rises.

Isolate the variable by dividing each side by factors that don't contain the variable.
