    The Correct equation is :
    • y = - 2x + 2
    \large \boxed{ \mathfrak{Explanation}}
    The given points are :
    • (4 , -6)
    • (0 , 2)
    we can see that the y – intercept (c) is 2, from point (0 , 2)
    now, let’s find the slope (m) :
    • \dfrac{2 - ( - 6)}{0 - 4}
    • \dfrac{2 + 6}{ - 4}
    • \dfrac{8}{ - 4}
    • - 2
    now, the equation of line will be :
    • y = mx + c
    • y = - 2x + 2

  2. Answer:
    y = 2x+2
    Step-by-step explanation:
    find gradient by using the gradient formula (m= y2-y1÷x2-x1)
    then find C
    y= mx+c
    the replace c and m in the equation (y=mx+c)
