Answer:
a)
b)
c)
Step-by-step explanation:
a) The slope / gradient is the coefficient of , so for a) it will be
.
C is the y-intercept, so the full equation will be .
b) Again, since the slope is 6, we know the coefficient of will be 6.
Now, we have a point on the line and so far, we know the equation is . The coordinates of the point are (2,-6). So now we substitute the y and x values into the equation in order to find C.
c) To find the gradient we must use the formula .
rise = change in y value
run = change in x value
so, the gradient
Now the equation is
Again, to find C we substitute any of the coordinates into the equation. I will use (-1,3).
so c) is
