A) Find the slope, x-intercept, y-intercept of the line (L):

Black_prince [1.1K]

Answer: 2, 1.5 , -0.75

(b) $4x-3y-10=0$

Step-by-step explanation:

Given

line is $3x+4y-6=0$

Converting it into intercept form

$\Rightarrow 3x+4y=6\\\\\Rightarrow \dfrac{3x}{6}+\dfrac{4y}{6}=\dfrac{6}{6}\\\\\Rightarrow \dfrac{x}{2}+\dfrac{y}{1.5}=1$

So, the x-intercept is $2$ and y-intercept is $1.5$

The slope is given by

$-\dfrac{\frac{1}{2}}{\frac{1}{1.5}}=-0.75$

(b) the line perpendicular to the above line and passing through $(1,-2)$

The slope of the required line

$m=-\dfrac{1}{-0.75}\\\\m=\dfrac{4}{3}$

Equation of the line is given by

$\Rightarrow \dfrac{y-(-2)}{x-1}=\dfrac{4}{3}\\\\\Rightarrow 3y+6=4x-4\\\Rightarrow 4x-3y-10=0$

The points A(12,7), B(12,−3), C(−2,−3), and D(−2,7) form rectangle ABCD. Which point is halfway between A and B? CLEAR CHECK (12

Flura [38]

We have that
coordinates are
A(12,7), B(12,−3), C(−2,−3), and D(−2,7)

i use the formula of midpoint between A and B
Xm=(x1+x2)/2 Ym=(y1+y2)/2
A(12,7) B(12,−3)
Xm=(12+12)/2=12
Ym=(7+(-3))/2=2

the point (12,2) is halfway between A and B
