Question #2405d

Answer 1

See the answer below....

Explanation:

If the equation of a straight line is written in the form `color(red)(ul(bar(|color(black)(y=mx+c)|`,then the slope of the line is `color(red)(m` and `Y` intercept is `color(red)(c`.

`x-y+7=0`
`=>y=x+7`

Comparing we get, the slope of the line is `color(red)(1`

Hope that helps...

Answer 2

`"slope "=1`

Explanation:

`"the equation of a line in "color(blue)"slope-intercept form"` is.

`•color(white)(x)y=mx+b`

`"where m is the slope and b the y-intercept"`

`"rearrange "x-y+7=0" into this form"`

`"add y to both sides"`

`xcancel(-y)cancel(+y)+7=0+y`

`rArry=x+7larrcolor(blue)"in slope-intercept form"`

`rArr"slope "=1`
