Help ? Pls ???????? Don’t know

Answer 1

Answer: y = -3x + 7

Step-by-step explanation:

The formula for calculating equation of line that passes through two points is given by :

$\frac{y-y_{1}}{x-x_{1}}$ = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$x_{1}$ = 4

$x_{2}$ = 3

$y_{1}$ = -5

$y_{2}$ = -2

substituting the values into the equation , we have :

$\frac{y-(-5)}{x-4}$ = $\frac{-2-(-5)}{3-4}$

$\frac{y+5}{x-4}$    = $\frac{-2+5}{3-4}$

$\frac{y+5}{x-4}$    = $\frac{3}{-1}$

$\frac{y+5}{x-4}$    = -3

y + 5 = -3( x - 4 )

y + 5 = -3x + 12

y = -3x + 12 - 5

y = -3x + 7

Answer 2

Answer:

y=-3x+7

Step-by-step explanation:

y=mx+b is the formula you are going to end up once completed.

This, by given two points:

(4,-5) (3,-2)

$\frac{-2-5}{3-4}$ = Point-Slope Intercept Form

$\frac{3}{-1}$ = After subtracting both from above

-3 = is your slope, decreasing.

Substitute -3 for y=mx+b

y=-3x+b

Use one of the given points (any) to find what b equals.

(4,-5)

x    y

-5=-3(4)+b

-5= -12+b

7=b

Final Equation:

y=-3x+7
