Answer:

y = -3x + 8

Step-by-step explanation:

I like to recommend this particular method for finding the slope of a  line through two given points:

Notice that if we move from (3, -1) to (5, -7), the horizontal distance covered (the "run") is 2 and the vertical change (the "rise") is -6.  Thus, the slope is m = rise / run = -6 / 2, or -3.

Starting with y = mx + b, replace y with -7 and x with 5, and m with -3:

-7 = -3(5) + b    ...  we must find b.

-7 = -15 + b    yields b = 8

and so the equation of this line is y = -3x + 8.

Answer:

9/10

1/2+2/5

Since these fractions have different denominators, we need to find the least common multiple of the denominators.The least common multiple of 2 and 5 is 10, so we need to multiply to make each of the denominators = 10

1/2 ∗ 5/5 = 5/10

5/2∗ 2/2= 4/10

Since these fractions have the same denominator, we can just add the numerators

5/10+ 4/10 = 9/10

Hey I need help just leave answer thx

Answer:

x = 61

Step-by-step explanation:

The angle above the line n adjacent to 2x - 6 is (x + 3) alternate angle.

Adjacent angles are supplementary, thus

2x - 6 + x + 3 = 180, that is

3x - 3 = 180 ( add 3 to both sides )

3x = 183 ( divide both sides by 3 )

x = 61

Is the function represented by the table linear
Bess [88]

Answer:

No, because it does not have a constant rate of change.

Step-by-step explanation:

On the <em>x</em><em> </em>side of the table, there is a constant rate of change (+1). However, on the y side, it is not. The first change is +7, the next +5, and the last +6. The rate of change has to be constant on both sides for the table to be considered linear.
