If a straight line y = mx + c passes through the intersecting point of 3x - y = 8 and x+ 2y = 5 which is perpendicular to the li
Sindrei [870]

Answer:

Point of intersection:

3x - y = 8 -  -  - (a) \\ x + 2y = 5 -  -  - (b)

2 × equation(b) + equation (a):

7x = 21 \\ x = 3 \\  \\ y = 3x - 8 \\ y = 1

Point of intersection = (3, 1)

Perpendicular line:

3x + 6y - 11 = 0 \\ 6y =  - 3x + 11 \\ y =  -  \frac{1}{2} x +  \frac{11}{6}

General equation of line:

y = mx + c \\ 1 = (2 \times 3) + c \\ c =  - 5

<u>Value</u><u> </u><u>of</u><u> </u><u>m</u><u>:</u>

<u>m \times m {}^{i}  =  - 1 \\ m \times  -  \frac{1}{2}  =  - 1 \\ m = 2</u>

Nana76 [90]

Answer:

Step-by-step explanation:

ab + c = d....subtract c from both sides

ab = d - c ....now divide both sides by a

b = (d - c) / a....or could also be b = (d/a) - (c/a)
