Question

Write an equation in slope-intercept form a line that is perpendicular to y = 3x-4 and that contains (-12, 2).

a. y = -1/3 + 2

b. y = -1/3 - 2

c. y = 3x + 26

d. y = 3x + 24

Answer #1

SOLUTION:: option (b)

THE equation is y=3x-4

the slope of this equation is m1=3

and the through point (-12,2)

lets the perpendicular equation slope is m2

we know that (m1)(m2)= -1

(3)(m2)= -1

now we can write the equation of perpendicular is y=m2x+b which is pass through the point (-12,2)

so

y=m2x+b

he equation of perpendicular is y=m2x+b

Consider the line with non-zero slope m and y-intercept b,
that is the line described by the equation y = mx + b where m is
not equal to 0. Use dot products of vectors to show that any line
perpendicular to this one must have a slope of -1/m. Also show that
in the case where m=0, any perpendicular line must be vertical (and
hence have undefined slope).
