More slope pls helpppppp
noname [10]
<h3>Answer:  C) 2</h3>

Explanation:

Recall that the general point-slope form is y - y_1 = m(x - x_1) where m is the slope and (x_1, y_1) is the point the line goes through. We see that the 2 and the m match up, so m = 2 is the slope.

Side note: We can rewrite that given equation into y - (-5) = 2(x - (-1)) to see that the line goes through the point (-1, -5)

HELP ASAP PLEASE!!! Explain how you will benefit most from improving your math skills.
RideAnS [48]

Answer:

Some of the most lucrative jobs are all about math. Most engineering fields are all about sharp math skills, whether it’s civil and mechanical or software engineering. Working in finance also obviously involves a lot of math, and what better way to make money than working in the field that’s all about money? You can also become a statistician or actuary; it’s not easy to find good statisticians, despite the need for them. If you want to earn good money, then you do need good math skills.Then again, you could use math in life anyway.
