Answer:
m = -1/2, y-intercept = -3, x-intercept = -6,0
Explanation:
M is the gradient (or slope) and is always in front of the x coefficient. -1/2 in this case.
To find the y-intercept, we have to know that it is at the point where the graph passes through the y-axis. At this point x = 0. So just substitute 0 for x and solve for y to give -3.
To find the x-intercept, do the opposite. When the graph passes through the x-axis, y = 0. So when y = 0, x = -6
