6(a)If the gradient of the straight line
ky = kx + x + 7 is 2,
find: (i) the value of k,
(ii) the y-intercept.
Vine

(i) k =1

(ii) y-intercept is 7

Step-by-step explanation:

Given line:

Divide all terms by k to get slope-intercept form of the line

Since the gradient (slope) of the line is 2:

The equation is now:

y - intercept is found when x = 0

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
