Answer: -10
Step-by-step explanation:
the slope is ALWAYS the number that is the closest to “x”
In this case, is -10 that is the closest
At the beginning, we don’t have the line (the equation) in a slope intercept form. This is y=mx+b
We have:
b (y-intercept)= 5
mx=-10x
You don’t write the slope with the “x”, that is why I wrote slope=-10
Never do this: slope=mx (just write m, the number that is the closest)
To convert a line into a slope intercept form, you need to add.
So, we have: -5=-y-10x
First add five to the other side of the equal sign
Now we have =-y-10x+5, which doesn’t work
But we need to put “y” on the other side
Then, we add again. Add “y” to the other side
And when we add, the negative sign,now, it’s a positive sign (+=addition)
That is how you get y=-10x+5
(The order of mx and the y-int. doesn’t matter as long as they’re on the right side)
