EXPLANATION
Let us find the gradient of the line:
by rewriting it in the slope intercept form.
We divide through by 4 now;
This is now in the form;
where
is he slope.
This implies that the slope of the line that is perpendicular to this line will be the negative reciprocal of .
Thus the perpendicular line has slope,
.
Let the perpendicular line have equation,
When we substitute the slope we have;
We substitute the point. 
to find c.
We substitute c to obtain;

Answer:
The distributive property
Step-by-step explanation:
We know that distributive property states a(b+c)=ab+ac. We can see that 3 is distributed to expression (2x-7) as
5+3(2x-7)=5+3*2x+3*-7
5+3(2x-7)=5+6x-21
Answer:
y² = x² - z²
Step-by-step explanation:
x² - y² = z²
Transpose y the other side
x² - z² = y²
or
y² = x² - z²
