Question

What do you do if you get given an equation to draw a graph which instead of `y=mx+c` it is `y=8-3`?

please answer I feel very worried as I have exams and don't understand it

Answer 1

`"see explanation"`

Explanation:

`y=8-3toy=5`

`color(red)(bar(ul(|color(white)(2/2)color(black)(y=c)color(white)(2/2)|)))`

`"is a special case of the equation of a straight line in that it"`
`"is a horizontal line parallel to the x-axis and passing "`
`"through all points in the plane with a y-coordinate equal to c"`

`"since it is parallel to the x-axis the slope "=0`

`"and the y-intercept "=c`

`y=5" passes through all points with y-coordinate of 5"`

`"here is the graph of "y=5`
graph{(y-0.001x-5)=0 [-20, 20, -10, 10]}
