How many solutions does the system below have?
3
y = -x + 8
4
3
y = -x - 5
4

I am taking the equations as 3y= -x+8

43y= -x-5

according to this there is only one unique solution

Step-by-step explanation:

se to identify solution identify type of line first

check the ratio of coffecient of variable and constant

if y1/y2 = x1/x2 = c1/c2 then the lines are coinciding and have infinite solution

if y ratio is not equal to x then 1 solution as I your question

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
