Question

Please help me solve the screenshot below.

Answer 1

The arrangement of the given equation in the slope - intercept form are

1. 
   `y=-x+4`
2. 
   `y=2x-5`

Explanation:

Given:

x + y = 4 and

y - 2x = -5

Slope - intercept form :

`y=mx+c`

Where,

m is the slope of the line.

c is the y-intercept.

When two points are given say ( x1 , y1 ) and ( x2 , y2) we can remove slope by

Slope,

`m=(y_(2)- y_(1))/(x_(2)- x_(1))`

Intercepts: Where the line cut X axis called X- intercept and where cut Y axis is called Y- intercept.

So, the Slope -intercept form of

x + y = 4 is
`y=-x+4`

and

y - 2x = -5 is
`y=2x-5`
