Solve the system of linear equations by substitution.
y = -2x + 10
y = x +1

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares

Polygon abcde is reflected to produce polygon a′b′c′d′e′. what is the equation for the line of reflection?

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x
