Answer:

Linear, y=6x-21

Step-by-step explanation:

Graph the answer to get an idea of the shape: linear.

Use y=mx+b and m=y2-y1/x2-x1 to find formula

m=y2-y1/x2-x1=3-(-9)/4-2=12/2=6

y=6x+b

9=6(5)+b

9-30=b=-21

y=6x-21

Which of the following linear equations represents the data chart?
BlackZzzverrR [31]

Answer: y = -x + 7

Step-by-step explanation:

The slope is \frac{5-6}{2-1}=-1, so we know the equation is of the form y=-x+b.

Substituting in the coordinates (1,6) to find b,

6=-1+b\\\\b=7

Thus, the equation is y = -x + 7

Can someone help me answer these two questions? I wanna know what's right and wrong. Please correct me if Necessary
agasfer [191]
Remember that the general equation of a line is y=mx+b, where:
m is the slope, and b is the y-intercept; so to find the y-intercept, solve for y and identify b.
Now, to find the x-intercept, just replace y in your line equation with 0, and solve for x
Lets apply those procedures to our two questions:

1. - y-intercept:
-10x+5y=40
5y=10x+40
y= \frac{10x+40}{5}
y=2x+8
Notice that now we have our line equation in the form y=mx+b with m=2 and b=8; sine b is the y-intercept, we can conclude that the y-intercept of our equation is 8.

x-intercept:
First, lets replace y with 0:
0=2x+8
And then, we can solve for x to find our x-intercept:
2x=-8
x= \frac{-8}{2}
x=-4
We can conclude that our x-intercept is -4; thus the correct answer in your list is the fourth one: x-intercept is -4; y-intercept is 8.

2. y-intercept:
5x+4y=80
4y=-5x+80
y= \frac{-5x+80}{4}
y=- \frac{5}{4} x+20
We can conclude that our y-intercept is 20.

x-intercept:
0=- \frac{5}{4} x+20
- \frac{5}{4} x=-20
x=( \frac{4}{5} )(20)
x=16
We can conclude that our x-intercept is 16; thus the correct answer in your list is, once again, the fourth one: x-intercept is 16; y-intercept is 20.
