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!

4x and 6y

im not sure though

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
