Question

Explain how to find the value of a line's y-intercept using its point-slope equation.

Answer 1

! To find the y-intercept of a line using its point-slope equation, you can substitute the coordinates of any point on the line into the equation and solve for the y-intercept. The point-slope equation is in the form y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope. Once you substitute the values and solve for y, the resulting value will be the y-intercept.

Answer 2

To find the value of a line's y-intercept using its point-slope equation, you can rearrange the equation to the form y = mx + b, where m represents the slope and b represents the y-intercept. The y-intercept is the value of y when x is equal to 0.
