15 POINTS!!!!!!! What is the equation of the line in slope-intercept form? Line on a coordinate plane. Line runs through points

suter [353]

Answer:

$y=\frac{4}{3}x+4$ is the equation of line in slope intercept form.

Step-by-step explanation:

Line runs through points begin ordered pair negative 3 comma 0 end ordered pair and begin ordered pair 0 comma 4.

First ordered pair: (-3,0)

Second ordered pair: (0,4)

We have two points and need to find equation of line in slope intercept form

$\text{Slope (m)}=\dfrac{y_2-y_1}{x_2-x_1}$

$\text{Slope (m)}=\dfrac{4-0}{0-(-3)}=\dfrac{4}{3}$

y-intercept, when x=0 , (0,4)

Equation of line in slope intercept form:

y=mx+b

where, $m=\frac{4}{3}$ and b=4

Required equation:

$y=\frac{4}{3}x+4$

Thus, $y=\frac{4}{3}x+4$ is the equation of line in slope intercept form.

Number 2 I need help on how to solve it

Hunter-Best [27]

Let's simplify the following expression:

$\text{ }\frac{\text{ \lparen2x}^4\text{ - y}^6\text{z}^{-4})^2}{\text{ 2x}^2\text{z}^3}\text{ }\cdot\text{ }\frac{\text{ 6x}^5\text{y}^{-4}\text{z}^{-5}}{\text{ \lparen2x}^6\text{y}^3\text{z}^{-3})^2}$

We get,

$\text{ }\frac{(\text{2x}^4\text{ - y}^6\text{z}^{-4})^2}{\text{ 2x}^2\text{z}^3}\text{ }\cdot\text{ }\frac{6x^5y^{-4}z^{-5}}{(2x^6y^3z^{-3})^2}$ $\text{ }\frac{(2x^4-y^6z^{-4})^2(6x^5y^{-4}z^{-5})}{(2x^2z^3)(2x^6y^3z^{-3})^2}$ $\text{ }\frac{(4x^8\text{ - 4x}^4y^6z^{-4}\text{ + y}^{12}z^{-8})(6x^5y^{-4}z^{-5})}{(2x^2z^3)(4x^{12}y^6z^{-6})}$ $\text{ }\frac{24x^{13}y^{-4}z^{-5}\text{ - 24x}^9y^2z^{-9}\text{ + 6x}^5y^8z^{-13}}{8x^{14}y^6z^{-3}}$

6y/8+12=84<br> What is y<br> How did you get that answer. Pls go step by step

vredina [299]

Answer:

6y/8+12-12=84-12

6y/8=72

8/6*6y/8=72*8/6

y=96

Step-by-step explanation:

first u get rid of the 12 by subtracting it from both side until u get 6y/8 =72. Then to isolate y u have to multiply the reciprocal of 6/8(8/6) by 6y/8, and u do the same thing to the other side. Then when they cancel out each other y would be left to equal 96.
