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:

$y = 2x +(-5)$

✅ $y = 2x - 5$

What is the value of this expression? (−4)4

alisha [4.7K]

It should be -16, assuming you are asking for -4*4. If you meant -4^4 (-4 to the fourth power) then the answer is 256.

Horatio wrote the multiplication facts for 8. which digit will not be in the ones place of the products?

dangina [55]

Answer:

Odd digits like 1, 3, 5, 7, and 9will not be at ones place of the products.

Step-by-step explanation:

If we look at multiplication facts of 8 we can see that,

8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96 etc

We can see that at the ones place, only even digits show up, like

0, 2, 4, 6, 8

But there is no odd digit at ones place.

So if Horation wrote the multiplication facts for 8, none of the odd digits will be there at ones place. Those digits include, 1, 3, 5, 7 and 9.
