To find the equation of the line in point-slope form, we can use the formula:<br /><br />y - y1 = m(x - x1)<br /><br />where (x1, y1) is a point on the line and m is the slope of the line.<br /><br />First, let's find the slope of the line using the given points (7,1) and (1,8).<br /><br />The formula for the slope is:<br /><br />m = (y2 - y1) / (x2 - x1)<br /><br />Substituting the coordinates of the given points, we have:<br /><br />m = (8 - 1) / (1 - 7)<br />m = 7 / -6<br />m = -7/6<br /><br />Now that we have the slope, we can choose one of the given points to substitute into the point-slope formula. Let's choose the point (7,1).<br /><br />Substituting the values into the formula, we get:<br /><br />y - 1 = (-7/6)(x - 7)<br /><br />Therefore, the equation of the line in point-slope form is:<br /><br />y - 1 = (-7/6)(x - 7)
