Best ResponseYou've already chosen the best response.03x+4y=7 4y=3x7 divide by 4 all through y=3/4x7/4 gradient of this equation is 3/4 (2,3) perpendicular is normally equal to 1 when you multiply both the gradients of the two that is; 3/4 * x = 1 x=4/3 this tends to be the gradient for the second equation to find the equation for (2,3) and we know the gradient is 4/3 y=mx+c y=4/3x + c (2,3) is represnted by (x,y) find change in y / change in x y+3/x+2 = 4/3 3(y+3)=4(x+2) 3y+9=4x+8 3y=4x+89 3y=4x1
