<span>What is the y-intercept of the plane whose equation is 4x + 5y + z = 20?

(0, 4, 0)

Which equation has intercepts at X(1, 0, 0), Y(0, 1, 0), and Z(0, 0, 2)?

2x + 2y + z = 2

Which equation is equivalent to x + 3y + z = 3?

4x + 12y + 4z = 12

Which of the following points lies in the plane 3x + 2y + 4z = 12?

(4, 3,2)

Hope these answer the questions. Have a nice day.</span>

5) Krystal bought three avocados for $4.

Delicious77 [7]

Answer:

5. beth can buy 49 avocados. 592 divided by 3 = 197 divided by 4 = 49

6. the painting will be 23 inches tall. 27 - 9 = 18 so 5 + 18 = 23

7. the photo will be 18 inches tall. 13 - 1 = 12 so 6 + 12 = 18

8. i think it's $273.08 . 37 divided by 10 = 3.7 x 74 = 273.8

Find the equation of the linear function represented by the table below in slope-intercept form.Answer: ?(Important: Please chec

Salsk061 [2.6K]

The Slope-Intercept form of the equation of the line is:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept.

The slope can be found with:

$m=\frac{y_2-y_1}{x_2-x_1}$

Choose two points from the table. These could be the points (1,-4) and (4,-19). You can set up that:

$\begin{gathered} y_2=-19 \\ y_1=-4 \\ x_2=4 \\ x_1=1 \end{gathered}$

Substituting values, you get that the slope of this line is:

$m=\frac{-19-(-4)}{4-1}=-5$

You can substitute the slope and the first point into the equation in Slope-Intercept form:

$-4=1(-5)+b$

Solve for "b":

$\begin{gathered} -4+5=b \\ b=1 \end{gathered}$

Therefore, the Equation of this line in Slope-Intercept form is:

$y=-5x+1$
