Write the slope intercept form of the equation of the line through the given points
garri49 [273]

Answer:

9) y = -3x - 4

10) y = -1/3x + 14/3

11) y = x - 1

12) y = -7/5x - 18/5

13) y = 3/5x + 9/5

14) y = -2x - 3

Step-by-step explanation:

For this explanation, let's use the last problem as the example. You would use the formula y=mx+b. The first thing you would need to find would be the slope, or m. So, you would find the slope and conclude the answer is -2. After that, you would solve for b and get the answer. Hope this helped!

Can someone please help me out with this its really urgent Ill mark brainliest
Alex73 [517]

Answer:

smart dot company c=.50t+12

communication plus c=2.50t

Step-by-step explanation:

smart dot has the starting point of $12 per month already so that would be your y-intercept with the equation being y=mx+b , y being the cost m being the amount of money per hour, x being the time spent, and b being the starting cost.

So with that smart dot would be c=.50t+12

with communication plus not having that starting point it would just be c=2.50t

In slope-intercept form, what is the equation of the line containing the points (−1, 2) and (2, −1)?
kvv77 [185]
Y2 - y1 over x2 - x1 = slope
2 - (-1) = 3
-1 - 2 = -3
the slope is 3/-3, or -1
y = -x
2 = 1 + 1
The equation of the line is y = -x + 1
