An equation for the line perpendicular to the line 4x + 8y = 7 having the same y - intercept as - 3x + 5y = - 2

4x + 8y = 7

8y = - 4x + 7

y = - 1/2x + 7/8 this equation has slope = - 1/2

line perpendicular to the line 4x + 8y = 7, so the slope = 2

same y - intercept as - 3x + 5y = - 2

y intercept means x = 0

5y = - 2

y = - 2/5

so

b = - 2/5

answer:

equation:

y = 2x - 2/5
