Question

Point B' is the image of point B after a reflection in a line. Write an equation of the line.

Answer 1

The line has a -2 slope and a 0 intercept. The line's equation is y = -2x.

What is en equation?

• Two expressions joined by the equals symbol ("=") form an equation.
• [2] The "left hand side" and "right hand side" of the equation are the expressions on either side of the equals sign.
• The right side of an equation is frequently considered to be zero. Providing the generality is not diminished, this can be achieved by deducting the right-hand side from both sides.
• The most frequent kind of equation has two polynomial sides, and is known as a polynomial equation or algebraic equation. A polynomial equation has one or more terms on each of its sides. For instance, the formula
• Ax2 + Bx + C y= 0

Formula for Lines

• The slope and y-intercept of the equation must be determined in order to determine the line's equation.
• The formula for calculating a line's slope is
• The line has a slope of 2, which.
• Let's determine the line's intercept;
• The equation's line is denoted by
• To determine c, we can choose point A and substitute its values.
• The line's equation is y = -2x.
