The line passes through the point (2,-9) and has a zero slope. Write the answer in slope-intercept form.

1 answer:

8 0

Answer:

Okay so for finding the equation of a line, which is a function, the equation is set to y, so you can eliminate A and B. When the slope of an equation is 0, we are saying that the y value of any point of the line is going to be the same, which is 9 from the given point (2,9).

So the answer is C. y=9

Write y=-5/8x+3 in standard form using integers?

Ivenika [448]

Answer:

standard form of given equation is 5x - 8y = -3

Step-by-step explanation:

$y= \frac{5}{8}x + 3$

Standard form of linear equation is Ax + By = C

First we remove the denominator 8

We multiply the whole equation by 8

So equation becomes

8y = 5x + 3

Now we move 5x to the left hand side, we subtract 5x on both sides

-5x + 8y = 3

Now we remove the negative side from -5x by dividing the whole equation by -1

5x - 8y = -3

a student earns a 90 on a test for missing one question incorrectly and earns a 70 for answering three incorrectly.What is the s

Rufina [12.5K]

I got -10

1. create two ordered pairs based on the data so (1, 90) and (3, 70)

2. plug into the slope formula so (70 - 90)/(3 - 1)

then it's -20/2, which is -10

Solve for x 0.5(5-7x)=8-(4x+6)

LekaFEV [45]

0.5(5 - 7x) = 8 - (4x + 6)
2.5 - 3.5x = 8 - 4x - 6
2.5 - 3.5x = 2 - 4x
-3.5x + 4x = 2 - 2.5
0.5x = - 0.5
x = - 0.5/0.5
x = -1 <==
