a new line is drawn through the point (-3,6) and perpendicular to the line with x-intercept (3,0) and y intercept (0,3) . what i
Klio2033 [76]

Answer:

The equation of the new line is y=x+9  or  y-6=(x+3)

Step-by-step explanation:

step 1

Find out the slope of the line with x-intercept (3,0) and y intercept (0,3)

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{3-0}{0-3}=-1

step 2

Find the slope of the new line perpendicular to the given line

we know that

If two lines are perpendicular,then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

m_1*m_2=-1

we have

m_1=-1 ----> slope of the given line

so

m_2=1 ---> slope of the new line

step 3

Find the equation of the new line in point slope form

y-y_1=m(x-x_1)

we have

m=1

(x_1,y_1)=(-3,6)

substitute

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

y-6=(x+3) ----> equation in point slope form

Convert to slope intercept form

y=mx+b

isolate the variable y

y=x+3+6

y=x+9

The truth table represents statements p, q, and r. p q r A T T T B T T F C T F T D T F F E F T T F F T F G F F T H F F F Which s
Lina20 [59]

We have been given the truth table for three variables p, q, and r. as shown below


p q r

A T T T

B T T F

C T F T

D T F F

E F T T

F F T F

G F F T

H F F F


Now we need to find Which statements are true for rows A and E for the following statements:

p ↔ q p ↔ r q ↔ p q ↔ r r ↔ p r ↔ q


To find that we need to use table of P <-> Q as shown in picture.

We know that if both statements are true for P and Q then only P <-> Q will be true. So using that trick we see that only q<->r and r<->q are the final answer as shown in the attached picture.
