<span>First we have to determine the slope of each lines by transforming to the slope-intercept form:
y=(3x-7/)4; m2= ¾y=(12x+6)/5, m3 = 12/5
The formula to be used in the proceeding steps is a=tan^-1(m1-m2)/1+m1m2=tan^-1(m1-m2)/1+m1m2
substituting, a=tan^-1(m1-3/4)/1+3m1/4=tan^-1(m1-12/5)1+12m1/5) =>(4m1-3)/(4+3m1)=(5m1-12)/(5+12m1)m1 = -1applying this slope
y -y1 = m(x-x1)
when y1 = 5 and x1 = 4 then,
y - 5 = -1(x-4)
y = -x +4+ 5 ; y = -x +9</span>

Step-by-step explanation:
Break the number within the radical symbol into 2 numbers: another number and a perfect square (when multiplied, they get the original number).
An example would be 48. The square root of 48 can be evaluated by breaking apart 48 into 16 (a perfect square) and 3 (another number). The square root of 16 is 4, so you take this number out of the radical symbol. Leave 3 within the symbol as it cannot be further reduced.
√48 = 4 √3.
