Answer:

y=1/2x-1

Step-by-step explanation:

The point of (0, -1) goes up 1 and 2 over to get to the next dot and the y-intercept is (0,-1) because that's where it hits the y.

Answer:

y=\frac{1}{2}x-1

Step-by-step explanation:

To find this answer in slope intercept form, you need to find the slope of the line as well as the y intercept. The line is clearly visible crossing the y axis at (0,-1), meaning that the y intercept is -1. The slope is also easy to find, because the line rises 1 unit for every two it moves to the left. This means that the slope is \frac{1}{2}. Therefore, the equation is y=\frac{1}{2}x-1. Hope this helps!

Is (-3, 2) a solution of -4r - 10y< - 9?
Blizzard [7]

Answer:

<em>The point (-3,2) is not a solution of the inequality</em>

Step-by-step explanation:

<u>Inequality</u>

Inequalities relate the left and the right side of an expression with an operator other than the equal sign.

The inequality given in the question is

-4r - 10y< - 9

There are many combinations of r and y that make inequality be true. For example, for r=1 and y=1

-4(1) - 10(1)< - 9

-14< - 9

This relation is true since -14 is less than -9.

Also, there are many combinations that make the given inequality be false.

For example, for r=2 and y=-1

-4(2) - 10(-1)< - 9

-8+10

2

This inequality is false.

Let's test the point (-3,2)

-4(-3) - 10(2)< - 9

12-10

2

Which is false, thus the point (-3,2) is not a solution of the inequality

Salsk061 [2.6K]

Answer: $1.35

Step-by-step explanation:

1.29 * 5% = 1.29 * 0.05 = 0.0645

0.0645 rounds down to 0.06

1.29 + 0.06 = 1.35
