what is the y-intercept of the line perpendicular to the line y = 3/4x + 3 that includes the point (3, 1)?

-5/4
3
-13/4
5

answer:

step-by-step explanation:

hello :

the line perpendicular to the line y = 3/4x + 3 is : y = ax+b when : a×3/4=-1

so : a = -4/3

y = -4/3 x +b

now calculate b : this line passes by the point (3, 1) meanes :   1 = -4/3(3)+b

so b= 5   so : y = -4/3 x +5

the y-intercept for this line when x= 0   : y = -4/3(0)+5   y = 5

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
