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
Answer:
B) y=12x
Step-by-step explanation:
We are given with the coordinates
Where represents the number of days.
represents the number of likes she got.
To model the equation using Kyle's data we find the slope using the given coordinate.
Let us say and
Slope formula ,
Plug in the above points now, we get
Now we use the point-slope formula,
Plugging the corresponding values.
Thus option is B is the correct answer.
