Given an equation in point-slope form, explain how to determine the coordinates of its y-intercept.
what is an equation of the line that is perpendicular to y-3=-4(x+2) and passes through the point (-5,7)
The slope of the line in the graph is 23-2-3. The y-intercept is -334-4. The equation of the line is y = 23-2-3x - 3+ 3+ 4- 4.
