Answer:
Explanation:
1. we pick 2 points from a graph...one is (0,-4) and the other is (1,2)
2. we find the gradient between the two points using this equation m=
3. we plug the value in the equation
4. m = 5/2
5. equation of a straight line is y = mx +c
-where c is the intercept of the graph and m is the gradient
-4=5/2(0)+c
c =-4
therefore
