If the constant term in the slope-intercept equation for a line determines what?
The x intercept.
What is the slope of the line for the equation y equals 3?
The slope equation is y = mx + b where m is slope for y = 3 we have y = 0 (x) +3 so m = 0 = slope So slope is zero line is constant y = 3
What is the equation of a horizontal and a vertical line using standard slope form?
We usually denote the slope of a line as M. Horizontal lines have a slope of zero. Mhorizontal line = 0 Verticle lines have a slope that is undefined. Note that the slope is not infinite, but is undefined. Mvertical line = undefined To write the equation of a horizontal or vertical line, we need to know if it's going to be a slope-intercept form or a point-slope form.
What is the equation of a line in general form with a point -3 0 and an undefined slope?
You can have infinitely many lines through one specific point, each with a different equation. If you want to have a general equation for ANY line that goes through that point, use the point-slope equation for a line, and use a variable for the slope.
What is an equation that represents a line?
y=mx+b is the equation of a line in the plane in slope intercept form. The m is the slope and the b is the y intercept. There are many other forms of equations of lines.
