Answer:
y = -3x + 9 is your answer.
Step-by-step explanation:
So your y-intercept is the slope. Here is the equation we are going to use:
y - y_1 = m(x - x_1)
y_1 = 0
x_1 = 3
m = -3.
y - 0 = -3(x - 3)
y - 0 = -3x + 9
y = -3x + 9 is your answer.
The standard form of the line is y = x - 3.
To find the standard form of a line, we need two pieces of information: the slope of the line and a point on the line. Given that the line has a y-intercept of -3, we know that the y-coordinate is equal to -3 when the x-coordinate is 0. So, we have the point (0, -3). We also know that the line passes through the point (3, 0). Using these two points, we can calculate the slope of the line:
Slope (m) = (change in y) / (change in x) = (0 - (-3)) / (3 - 0) = 3/3 = 1.
Now that we have the slope and a point on the line, we can use the point-slope form of a line to write the equation:
y - y1 = m(x - x1), where (x1, y1) are the coordinates of a given point and m is the slope of the line.
Substituting the values of (x1, y1) = (3, 0) and m = 1 into the equation, we get:
y - 0 = 1(x - 3)
y = x - 3
Therefore, the standard form of the line that contains a y-intercept of -3 and passes through the point (3,0) is y = x - 3.

The equivalent value of the fraction is A = 64
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the numerator of the fraction be p
where the value of p = 16
Let the denominator of the fraction be q
where q = 1/4
Now , the fraction is A = p/q
On simplifying the expression , we get
So , the left hand side of the equation is equated to the right hand side by the value of p/q
A = 16 / ( 1/4 )
A = 16 x 4
On further simplification , we get
A = 64
Therefore , the value of A = 64
Hence , the expression is A = 64

Answer:
{-1, 3}
Step-by-step explanation:
Please use " ^ " to denote exponentiation: f(x) = x^2 - 2x - 3.
To find the zeros of this quadratic, set it equal to zero first:
f(x) = x^2 - 2x - 3 = 0.
Now factor this result: (x - 3)(x + 1) = 0.
The zeros are {-1, 3}
