The question is incomplete other wise it is really easy to solve if you now how to make the line of equation. As we know the formula to calculate the line of equation is y - y1 = m (x - x1)

Where m is the slope. y1 is the first y co ordinate. x1 is the first x co ordinate.

And the formula for slope is as we know is m = y2 - y1 divided by x2 - x1.

Where m is the slope. y2 is the second y co ordinate. y1 is the first y co ordinate. x2 is the second x co ordinate. x1 is the first x co ordinate.

In the picture a=2, b=4a, b=4•2=8
1st picture a=3, b=4a, b=4•3=12
2nd picture a=0.5, b=4•0.5=2
3rd picture a=2.5, b=4•2.5=10
4th picture a=4, b=4•4=16, but in the picture b=10 therefore, this rectangular is NOT similar to rectangular ABCD.

Giving 30 points to whoever helps me.Fasttttt and no wrong answers.

The answer is y = -3x + 10.
The rest is not linear since the rest is not in the form of y = mx +b (a type equation for a line).

Have an awesome day! :)

The slope of a line that is perpendicular to a line whose equation is −2y = 3x + 7 is $\frac{2}{3}$
