10. Choose the correct answer. perpendicular to 'y=5/2x-6' and has the point (5,-7) a. y= 2/5x-9

b. y= -5/2x+14

c. y= 5/2x-39

d. y= -2/5x-5​

d

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = x - 6 ← is in slope- intercept form

with slope m =

Given a line with slope m then the slope of a line perpendicular to it is

= - = - = - , then

y = - x + c ← is the partial equation

To find c substitute (5, - 7) into the partial equation

- 7 = - 2 + c ⇒ c = - 7 + 2 = - 5

y = - x - 5 ← equation of perpendicular line → d

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

ian gonna lie that is way to much
