(Solving for a specified variable, equations of lines) When writing the equation of a line in college algebra, we will start with the point-slope form of line, y - y? = m(x-x?), and we will solve it for y to write it inslope-intercept-form, y = mx + b. Substitute the given point and slope into the point-slope form and then solve for y so your equation is in slope-intercept form.a) x? = 2, y? = 3, m = 4b) x? = 5, y? = -5, m = -2
