Write an equation of the line that passes through the point (–1, 4) with slope 2. A. y+1=−2(x−4) B. y+1=2(x−4) C. y−4=2(x+1) D.
In-s [12.5K]

Answer:

y-4=2\,(x+1)

which agrees with answer C in your list of possible answers.

Step-by-step explanation:

We can use the general point-slope form of a line of slope m and going through the point (x_0, y_0):

y-y_0=m(x-x_0)

which in our case, given the info on the slope (2) and the point (-1, 4) becomes:

y-y_0=m\,(x-x_0)\\y-4=2\,(x-(-1))\\y-4=2\,(x+1)

Three medium pizzas cost $10.50. How much does it cost to buy 10 medium pizzas?
olga nikolaevna [1]
Hello! First off, we can find the unit rate on what it would cost per pizza. Divide the total amount by the number of pizzas. 10.50/3 is 3.5. It costs $3.50 per medium pizza. Now, we can multiply that amount by 10 to get the amount for 10 pizzas. 3.5 * 10 is 35. There. It costs $35 to buy 10 medium pizzas.
