Question

OMG HELPP IM GOING TO FAILL!!!!!!!

Choose the graph of the system of equations. A graph with days on the x axis and number of pages on the y axis. There are two lines. One line begins at the origin and passes through the point 20 comma 200. The other line begins at zero comma 40 and passes through the point 20 comma 200. A graph with days on the x axis and number of pages on the y axis. There are two lines. One line begins at zero comma 280 and passes through the point 20 comma 80. The other line begins at zero comma 240 and passes through the point 20 comma 80. A graph with days on the x axis and number of pages on the y axis. There are two lines. One line begins at the origin and passes through the point 25 comma 200. The other line begins at 5 comma zero and passes through the point 25 comma 200. A graph with days on the x axis and number of pages on the y axis. There are two lines. One line begins at the origin and passes through the point 7 comma 65. The other line begins at zero comma 40 and passes through the point 7 comma 65.

Answer 1

Explanation:

Ok, so break this down into each line and Graph

1) pages on the y and days on the bottom (x)

a) begins at origin, passing through the point (20,200)

200 - 0 / 20 - 0 = 200/20 = 10

therefore this line has a slope of 10

y = 10x

b) begins at (0,40) [also known as y-intercept], passes through (20,200)

200 - 40/20-0 = 160/20 = 8

Slope = 8

y = 8x +40

Graph is shown at bottom

Repeat the process for the rest

Break it down like this

2) A graph with days on the x axis and number of pages on the y axis.

There are two lines.

One line begins at (0,280) and passes through the point (20,80)

The other line begins at (0,240) and passes through the point (20,80)

80 - 280/ 20 - 0 = Slope 1

80 - 240/ 20 - 0 = Slope 2

(0, #) = y-intercept = #

3) A graph with days on the x axis and number of pages on the y axis.

There are two lines.

One line begins at the origin and passes through the point (25,200).

The other line begins at (5,0) and passes through the point (25,200).

200 - 0/25 - 0 = Slope 1

200 - 0 / 25 - 5 = Slope 2

(0, #) = y-intercept = #

4) A graph with days on the x axis and number of pages on the y axis.

There are two lines.

One line begins at the origin and passes through the point (7,56).

The other line begins at (0,40) and passes through the point (7,56)

56-0/ 7-0 = Slope 1

56-40 / 7-0 = Slope 2

(0, #) = y-intercept = #
