# Write the equation of a line with given slope and Y-intercept, (0,-5) ⚑ Flag

To answer your question, I need the given slope.But all you do is just plug in your known values to y= mx+b.Since we know the y-intercept already, just plug that in:y = mx - 5The rest, you just plug in and solve for whatever value is missing. In this case, all you need to do is plug in the slope, and you're done.

well, as stated previously this is a point slope method. Any line can be expressed with two points or a point and a slope. The equation y = mx + b. m and b are constants. m is the slope and b is the vertical shift. In point slope problems, you are given the slope, plug in the x and y values of the point given to find b. If you have two points the line is given in standard form: (y-a) = c(x-b). Two points will be given to you, usually one is the intercept. then just plug in and solve. If you cannot solve the standard function, find the slope between the points and use the point slope form
