The result is a line perpendicular to y=3x-2 This line has the following equation: y =mx + b, where m = slope
Remember that the product of the slopes of two perpendicular lines is always = -1 (or in other term one is the reciprocal inverse of the other) so the first slope = 3 and the sope perpendicular to 3 will be - 1/3. Then the new equation is y = - 1/3(x) + b How to calculate b? This line passes through (6, 8), that means (x=6 and y=8) . Plug these values in y = -1/3 (x)+b:3 8=(-1/3)(6) + b; 8= - 2 + b and b = 10 Te final equation is y = - 1/3.x+10 (answer A)
The area of the kite is made up of two pairs of congruent triangles. Find the area of these and add to get the kite's area. (area of triangle = (1/2)(base)height))
