Write an equation for the line with a slope of 2 snd the points (5,10) and (1,2)

y = 2x

work:

let's use the equation y = mx + b, m stands for slope and b stands for the y intercept.

we know the value for the slope, so let's plug it into the equation.

y = 2x + b

okay, so to find the missing value, b, plug in the y and x values.

10 = 2(5) + b

now, solve.

10 = 10 + b

0 = b

so, now we now b has a value of 0.

so, the slope is 2, so our equation is y = 2x. hope this helps!

d) -1

step-by-step explanation:

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
