Answer:
240 units squared
Step-by-step explanation: Pythagorean theorem and then multiply base times height / 2
4x - y = 2
y = 4x
and 4x + y = 6
As all three of their gradients have been inverted (-1/m), meaning they are perpendicular.
Answer:
Yes
Step-by-step explanation:
Since the line passes through the origin, when calculating the slope of the line, we can make use of the origin as a point. So pests say (x1, y1) = (0,0) and (x2,y2) is (a,b). Hence the slope is b/a.
Now we now act on this information to solve the problem. Firstly, we know that the slope is negative, this means either a or b is negative but both are not negative. Secondly, b is greater than a. This mean b is the positive term as both terms cannot be negative.
