2x + 5y = 10
Change to y = mx + b
subtract 2x from both sides
5y = -2x + 10
divide both sides by 5
y = -2/5x + 2
slope = -2/5

we have

2x + 5y = 10

we know that

the formula to calculate the slope is equal to

m=\frac{(y2-y1)}{(x2-x1)}

Let

A( 5,0)\\B( 0,2)

Step 1

Find the slope AB

mAB=\frac{(2-0)}{(0-5)}  \\ \\ mAB=-\frac{2}{5}

therefore

the answer is the option B

-\frac{2}{5}
