Write The line through (0,-2) and (4,6) in point form

Anna35 [415]

(0,-2)(4,6)
first we find the slope by using the slope formula : slope(m) = (y2 - y1)/(x2 - x1)

slope(m) = (6 - (-2) / (4 - 0) = (6 + 2)/4 = 8/4 = 2

point slope form : y - y1 = m(x - x1)... 2 answers are possible

y - y1 = m(x - x1)
slope(m) = 2
using points (0,-2)....x1 = 0 and y1 = -2
y - (-2) = 2(x - 0)
y + 2 = 2(x - 0) <=== here is one answer

y - y1 = m(x - x1)
slope(m) = 2
using points (4,6)...x1 = 4 and y1 = 6
y - 6 = 2(x - 4) <== here is the other answer

A straight has slope equals to 12 and y-intercept equals to -5. What's the equation for this straight line?

Rama09 [41]

Answer:

$\large{ \tt{❃ \: EXPLANATION}} :$

We're provided : Slope of straight line ( m ) = 12 & y - intercept ( c ) = - 5 and We're asked to find out the equation for this straight line.

You'll have to know : Equation of straight line in slope intercept form : y = mx + c where m is the slope & c is the y-intercept.

$\large{ \tt{❁ \: LET'S \: START}} :$

Using Slope - intercept form of equation of straight line :

$\boxed{ \large{ \tt{❈ \: y = mx + c}}}$

- Plug the values :

$\large{ \tt{↬y = 12x + ( - 5)}}$

$\large{ \tt{↬ \: y = 12x - 5}}$

$↬\large{\tt{12x - 5 = y}}$

$↬ \large{ \boxed{ \bold{ \tt{12x - y - 5 = 0}}}}$

Hence , 12x - y - 5 = 0 is the required equation.

Find the distance and midpoint between the points (7, 3) and (-2,-5).

pochemuha

(7,3)
(-2,-5)

Distance:-

$\\ \rm\Rrightarrow \sqrt{(7+2)^2+(3+5)^2}$

$\\ \rm\Rrightarrow \sqrt{9^2+8^2}$

$\\ \rm\Rrightarrow \sqrt{81+64}]/tex][tex]\\ \rm\Rrightarrow \sqrt{145}$

$\\ \rm\Rrightarrow 12(approx)$

Midpoint

$\\ \rm\Rrightarrow \left(\dfrac{7-2}{2},\dfrac{3-5}{2}\right)$

$\\ \rm\Rrightarrow \left(\dfrac{5}{2},\dfrac{-2}{2}\right)$

$\\ \rm\Rrightarrow \left(\dfrac{5}{2},-1\right)$

if ZA and ZB are supplementary angles. if mZA = (3x-23) and mZB= (2x-12) then find the measure of ZB

Brilliant_brown [7]

Answer:

mZB= 74

Step-by-step explanation:

ZB+ZA=180

3X-23+2X-12=180

5X-35=180

5X=180+35

5X=215 (then divide both sides by 5 to x be left alone.)

X=43....so ZB=2(43)-12

=86-12=74
