Find the distance between the points ( 19 , 16 ) and ( − 13, 10 )

Inessa [10]

Answer:

$\sqrt{1060}=32.55..... or 32.6$

Step-by-step explanation:

$\sqrt{(-13-19)^2+(10-16)^2}$

$\sqrt{(-32)^2+(-6)^2}$

$\sqrt{1024+36}$

$\sqrt{1060}=32.55..... or 32.6$

Write an equation in slope-intercept form of the line shown.

7nadin3 [17]

Answer:

$y = 2x - 5$

Step-by-step explanation:

Find the slope using the points, (1, -3) and (3, 1):

$slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 -(-3)}{3 - 1} = \frac{4}{2} = 2$

m = 2

Find the y-intercept (b) by substituting x = 1, y = -3, and m = 2 in $y = mx + b$

$-3 = (2)(1) + b$

$-3 = 2 + b$

Subtract 2 from both sides

$-3 - 2 = 2 + b - 2$

$-5 = b$

$b = -5$

Plug in the value of m and b into the slope-intercept form equation, $y = mx + b$ .

Thus:

$y = 2x +(-5)$

✅ $y = 2x - 5$
