How do you come up with 700-799 using ratio

If sec theta = 5/3 and the terminal point determined by theta is in quadrant 4, then

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

The description below represents function a and the table represents function b: function a the function is 5 more than 3 times x. function b x y −1 2 0 5 1 8 which statement is correct about the slope and y-intercept of the two functions? (1 point) their slopes are equal but y-intercepts are not equal. their slopes are not equal but y-intercepts are equal. both slopes and y intercepts are equal. neither slopes nor y-intercepts are equal.
