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

#"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]}
