Find an equation for the line with the given properties. Express your answer using either the general form or the slope-intercept form of the equation of a line. Slope \( =-7 ; y \)-intercept \( =3 \) The equation is (Type an equation. Simplify your answer.)

To find the equation of a line in slope-intercept form, we can use the formula \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept. Here, the slope \( m = -7 \) and the y-intercept \( b = 3 \). So the equation is: \( y = -7x + 3 \). This is the slope-intercept form of the equation for the line. If you prefer the general form, you can rearrange it to \( 7x + y - 3 = 0 \). Either form works, depending on your needs!
