To find the x intercept, plug zero in for y and solve.
To find the y intercept, plug zero in for x and solve.
6(0) + 7y = -4
y = -4/7
(0, -4/7)
6x +7(0) = -4
6x = -4
x = -4/6 = -2/3
(-2/3, 0)
Answer:
no
Step-by-step explanation:
The -xy term is 2nd-degree, since the sum of the exponents of the variables is 1+1 = 2. The highest degree term is not first-degree, so the equation is not a linear equation.
There is a probability of 22.66% that their average catch is less than 31.5 pounds
<h3>What is
z score?</h3>
The z score is used to determine by how many standard deviations the raw score is above or belaw the mean. It is given by:
z = (raw score - mean)/ (standard deviation ÷ √sample)
Given that, mean = 32, std = 4, sample = 36, hence:
For 31.5:
z = (31.5 - 32) / (4 ÷√36) = -0.75
P(z < -0.75) = 0.2266
There is a probability of 22.66% that their average catch is less than 31.5 pounds

Answer:
a) y= x+7
The slope is 1 and the y intercept is 7
b) y = -3x
The slope is -3 and the y intercept is 0
Step-by-step explanation:
The slope intercept form of the equation of a line is
y = mx+b where m is the slope and b is the y intercept
a) y= x+7
The slope is 1 and the y intercept is 7
b) y = -3x
The slope is -3 and the y intercept is 0
