you first plug (substitute) in y

-3x - 3(-5x-17)=3

then distribute

-3x+15x+51=3

now combine like terms

12x+51=3

subtract to get 12x by itself

12x=3-51 or 12x=-48

lastly divide by 12 to find x

12x/12=-48/12

x=-4

now find y by plugging x into the other equation

y=-5(-4)-17

y=3

(-4,3)

What is the equation of the line that passes through the point (-1, -7) and has a<br> slope of 2?

slava [35]

Answer:

y=2x-5

Step-by-step explanation:

The slope-intercept form of an equation looks like y=mx+b. Where m is the slope and b is the y-intercept. The slope is already given to us, so m is 2.

To find b use the equation $b=y_1-m*x_1$ . So, to find the y-intercept use b=-7-(2*-1). This equals b=-5.

So, plug in the values to get the final equation y=2x-5.
