Find the slope-intercept form of an equation of the line perpendicular to the graph of x – 3y = 5 and passing through (0, 6).
Artyom0805 [142]

Answer:

y=-3x+6

Step-by-step explanation:

x-3y=5

y=1/3x-5/3

slope of perpendicular line is -3 (opposite reciprocals)

y=mx+b

x=0 and y=6

6=3x+b

6=3(0)+b

6=b

y=-3x+6

Which is the area of triangle LMN? Group of answer choices 24 square units 27 square units 54 square units 48 square units
irina [24]

Answer:

√65/2 square units

Step-by-step explanation:

Find the diagram attached

Area of the triangle = 1/2 * base * height

To get the base and height, we will use the distance formula;

Area of the triangle LMN = 1/2 * LM * MN

For MN

Given the coordinate M(3, 2) and N(1, 3)

MN = √(3-2)²+(1-3)²

MN = √1²+(-2)²

MN = √1+4

MN = √5

For LM;

Given the coordinate L(1, -1) and M(3, 2)

LM = √(2-(-1))²+(3-1)²

LM = √(2+1)²+(2)²

LM = √3²+(2)²

LM = √9+4

LM = √13

Area of the triangle LMN = 1/2 * √13 * √5

Area of the triangle LMN = √65/2 square units
