Question

A line has a slope of –2 and passes through the point (4, –9). Which is the equation of the line?


Question 3 options:


y = –2x – 17



y = –2x – 1



y = –2x + 1



y = –2x + 17

Answer 1

Here you're given the slope of the line in question, along with a point through which the line passes. Use the "point-slope" formula for the equation of a straight line:

y-k = m(x-h), where (h, k) is the given point and m is the given slope.

Answer 2

Once you've done that, you could solve this equation for y if necessary.

Answer 3

There is a website called Desmos, which allows you to graph easily if you want to do it that way

Answer 4

thanks!

Answer 5

it would be y=-2x-1

Answer 6

your welcome :)
