M(slope)= -5/4 point-slope(y-y1=m(x-x1)) so it would be y-5= -5/4(x+4)
Answer: 8x + 7 = ?
Step-by-step explanation: There isn't anything on the other side so all I can do is simplify the left.
Answer:

Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:

In which m is the slope and b is the y-intercept.
Perpendicular lines:
When two lines are perpendicular, the multiplication of their slopes is -1.
Perpendicular to y=1/8x+2
This line has slope 
So, for the line we want to find the equation, we have that:


So

Find the equation of the line through point (1,−5)
This means that when
. We use this to find b. So:



The equation of the line is:

X=2 because when you multiply 8 x 2=16 - 4=12
8(2)-4=12
