How to find slope and y intercept from the equation ax+by=c?

Mathematics
1 answer:
melisa1 [442]3 years ago
5 0

solve for "y" so it is in the form y = mx + b.   "m" is the slope and "b" is the y-intercept.

ax + by = c

      by = -ax + c          <em>subtracted "ax" from both sides</em>

       y  = (-a/b)x  + c/b     <em>divided both sides by "b"</em>

Answer: slope is -a/b    and y-intercept is c/b

What is the slope of this graph? −3 −1/3 1/3 3 Number graph ranging from negative 10 to 10 on both the x and y axis. A line pass
fiasKO [112]

Answer:

-3

Step-by-step explanation:

The slope is the ratio of the change in y-coordinates to the change in x-coordinates:

... (5 -(-1))/(-1-1) = 6/-2 = -3

A wedding website states that the average cost of a wedding is $25,809. One concerned bride hopes that the average is less than
lapo4ka [179]

Answer:

1)

Null hypothesis            H₀ : μ = 25,809

Alternative hypothesis H₁ : μ < 25,809

2) Test Statistic = -1.44

3) Conclusion:

The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.

Step-by-step explanation:

Given the data in the question;

Sample mean x" = 24,638

sample size n = 46

standard deviation σ = 5531

level of significance ∝ = 0.10

NULL and ALTERNATIVE HYPOTHESIS

Null hypothesis            H₀ : μ = 25,809

Alternative hypothesis H₁ : μ < 25,809

TEST STATISTICS

Z = (x"-μ) / σ√n

we substitute

Z = (24,638 - 25,809) / (5531/√46)

Z = -1171 / 815.5

Z = -1.44

Test Statistic = -1.44

Now, from normal z-table;

P-value = P( Z < -1.44 ) = 0.0749

P-value = 0.0749

Since P-value ( 0.0749 ) is less than level of significance ( 0.10 ), we reject H₀.

Conclusion:

The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.

What is the equation in slope-intercept form of the linear function represented by the table? x y –6 –18 –1 –8 4 2 9 12 y = nega
svetoff [14.1K]

Answer:

y = 2 x minus 6

Step-by-step explanation:

(-6,-18) and (-1,-8)

Slope: (-8 - -18)/(-1 - -6)

10/5

2

y = 2x + c

-8 = 2(-1) + c

-8 = -2 + c

c = -6

y = 2x - 6

y = 2x - 4

Observe the expression below and select the true statement(s).
DENIUS [597]

Answer: The 9 in the second term is a coefficient that is true. I think that is the only thing that is true. There may be one more thing that is true.

The 10 in the third term is not  a coefficient.

The 2 is not a constant

the x is not an exponent.

those are the ones that I'm sure about.

Please correct anything if i'm wrong.

:)
