A:
Preview: ... y=6*x+5/8 has a slope m=6 and a y-intercept b=5/8. Now to find the slope of the perpendicular line, simply flip the slope m=6 to get m=1/6. Now change the sign to get m=-1/6. So the perpendicular slope is m=-1/6. Now let's use the point slope formula to find the equation of the perpendicular line by plugging in the slope m=6 and the coordinates of the given point . y-y[1]=m(x-x[1]) Start with the point slope formula y-3=(-1/6)(x-7) Plug in m=-1/6, x[1]=7, and y[1]=3 y-3=(-1/6)x+(-1/6)(-7) Distribute y-3=(-1/6)x+7/6 Multiply y=(-1/6)x+7/6+3 Add 3 to both sides. y=(-1/6)x+25/6 Combine like terms. So the equation of the line perpendicular to 8y-48x=5 that goes through the point (7,3) is y=(-1/6)x+25/6. ----------------------------- # 15 Note: attached is the graph From ...
