Using the slope and the y-intercept, graph the line represented by the following equation. complete your work in the space provided or upload a file that can display math symbols if your work requires it. include the graph of the linear equation, 2x - y + 4 = 0.

see the explanation

The graph in the attached figure

Step-by-step explanation:

we have

This is the equation of the line in standard form

Convert to slope intercept form

where

m is the slope

b is the y-intercept

Isolate the variable y

Adds y both sides

Rewrite

therefore

the slope m is

The y-intercept is the point (0,4)

To graph a line we need two points

using the slope

The slope of (+2) tells us that for every unit increment (i.e. +1) of the x

value, the y  value changes by ( +2)

we have the point (0,4)

so

For x=0+1=1 -----> y=4+2=6

therefore

we have the points (0,4) and (1,6)

Plotting these coordinates on the Cartesian plane and drawing a straight line

see the attached figure

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
