Find the slope of the following lines ​

Mathematics

Hey there!

The slope of the given line is -2

We can solve this by doing rise over run. Pick a point and see how much it goes up (positive number) or down (negative number) - numerator - and put it over the number it goes left (negative number) or right (positive number) - denominator. For example, in this situation, we can start at the point (2, -1), and we can see that we go up 2 and left 1, until we get to the next point (1, 1). Therefore, our fraction would be \frac{2}{-1}, or -2.

Hope it helps and have a great day!

If the expression ax(2x + y - 5) simplifies to 6x² +3xy - 15x, what is the value of a?
nata0808 [166]
Since:
ax(2x + y - 5) = 6x^2 +3xy - 15x,

we should factor X out of the second equation to find out the value of a:
6x^2 + 3xy - 15x =
x(6x + 3y - 15),

Now that we factored X out, to find a, we need to find the other common factor:

(6x + 3y - 15) / (2x + y - 5),

which is 3.

Hence the value of a is 3
