3x-y+6=0.......(1)

y+2x=5........(2)

[m1]slope of line 1=- coefficient of x/coefficient of y=3

[m2]=]slope of line 2=- coefficient of x/coefficient of y=-2

we have

tan ø= $\frac{m1 - m2}{1 + m1m2}$

tan ø= $\frac{3+2}{1 + 3×-2}$

tan ø= $\frac{5}{-5}$

tan ø=-1

ø=135°

obtuse angle between the pair of line is 135°

y = 1

Step-by-step explanation:

Every point on a horizontal line has the same y-value. Use the y-value of the point to find the equation of the horizontal line.

Hope it is helpful....
Choose the equation of the horizontal line that passes through the point (-5,1)
