i get the concept of slopes and such but i’m not rlly sure how to put a word problem in a graph? can someone please help out?

Answer:
see below
Step-by-step explanation:
Read the words down to the point where it says "graph this equation." Then, it's not a word problem anymore—it's a problem of graphing the given equation.
c = 2t +8
The "y-intercept" is the value of "y" when t=0. It is 8. This is the cost of a pizza with 0 toppings.
The slope is the coefficient of t. It is 2. This is the increase in the cost of a pizza when 1 topping is added. The slope is the cost of a topping.
__
Be aware that the grid on this graph shows squares, but the vertical dimension of the square is $2 while the horizontal dimension is 1 topping. That is, a line with a slope of 2 will lie on the diagonal of a grid square.

<em>Additional comment</em>
We call the point where the graph crosses the vertical axis the "y-intercept." It is called that here, even though "y" is not in the equation or on the graph anywhere. It should rightfully be called the "c-intercept", since the vertical axis shows the value of c, the cost of the pizza.

Step-by-step explanation:
I'll do 2.
Alright,Alex let say we have factored a quadratic into two binomial, for example
If we set both of those equal to zero
We can used the zero product property in this case to find the roots of the quadratic equation.
This means that
This means we set each binomal equal to zero to find it root.
So our roots are negative 3/5 and negative 2/3 using zero product property

Step-by-step explanation:
The minimun distance between a point and a plane is the perpendicular distance. The formula is
d =
where , A=4, B=3, C=1 and D=-10. So, the distance is
d =
d =
d = .
