SOMEONE PLZ ANSWR ITS AN INTREST RATE QUESTION NO LINKS plz also explain how you got the answer and the formula

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.

Which of the following describes the graph of y--4x-36 compared to the parent square root function? stretched by a factor of 2, reflected over the x-axis, and translated 9 units right stretched by a factor of 2, reflected over the x-axis, and translated 9 units left stretched by a factor of 2, reflected over the y-axis, and translated 9 units right stretched by a factor of 2, reflected over the y-axis, and translated 9 units left save and exit next submit

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x
