answer: 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!
