Write an equation of the line containing the point (1,- 3) and perpendicular to the line 6x - y = 4

y = 6x-4

Slope = 6

Since the line is perpendicular slope = -1/6

Equation of the line is

y +3 = -1/6(x-1)

Multiply through by 6

6y +18 = -x + 1

6y = -x -17

Hope this helps.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

irrational, cannot
