The equation of this line is y = 7x + 3. What would happen to the graph if the equation was changed to y = 2x + 6?
PSYCHO15rus [73]

Answer:

From the graph,

  • The line y = 7x + 3 is represented by a red line with y-intercept (0, 3)
  • The line y = 2x + 6 is represented by a blue line with y-intercept (0, 6)

it is clear that the slope and y-intercept  have been changed.

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where m is the slope and b is the y-intercept

Given the equation of a line

y = 7x + 3

comparing with a slope-intercept form of the line equation

y = mx+b

Here,

The slope = m = 7

y-intercept  = b = 3

Now, the equation changed to y = 2x + 6

y = 2x + 6

comparing with a slope-intercept form of the line equation

y = mx+b

Here,

The slope = m = 2

y-intercept  = b = 6

Thus, if the equation was changed to y = 2x + 6, the slope and y-intercept also get changed from m = 7 to m = 2 and b = 3 to b = 6 respectively.

The lines of both equations is also attached.

From the graph,

  • The line y = 7x + 3 is represented by a red line with y-intercept (0, 3)
  • The line y = 2x + 6 is represented by a blue line with y-intercept (0, 6)

it is clear that the slope and y-intercept  have been changed.

Kyle caught 9 insects for his science project in the first week. he caught 13 insects in the second week. what is the percent in
Tcecarenko [31]
To find the percent increase, you will find the difference between the two amounts and then divide by the starting amount.

13 - 9 = 4
4/9 = 0.44...
This is approximately 44%.

There was an approximate 44% increase.

I really need some explanation cause like I’m confused
LekaFEV [45]

Answer:

85 ft

Step-by-step explanation:

Pythagorean Theorem:

a^{2} + b^{2}  = c^{2}

Where a and b are sides and c is the hypotenuse.

Substitute:

13^{2} + 84^{2} = c^{2}

169 + 7,056 = c^2

7,225 = c^2

\sqrt{7,225}  = \sqrt{c^2}

85 = c

85 feet
