Best Answer

The equation of a straight line in slope intercept form is y = mx + c, where y is the y coordinate of any point, x is the x coordinate of that point, m is the slope and c is the y intercept. Therefore, the equations that correctly describe a line with a y intercept of 7 would be: y = mx + 7. The individual slope would then have to be substituted into this equation.

There are an infinite number of possibilities.

y=2x+3, 3y=x+9

Y = ('x' times any number) + 7

It will be any of the equations that has the same slope of y = 5x+9 but with a different y intercept

The y-intercept, together with the slope of the line, can also be used in graphing linear equations. The slope and y-intercept of a line can be obtained easily by inspection if the equeation of the line is of the form y=mx+b where m is the slope and b is the y-intercept.

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.
