Find the y-coordinate of point M. the midpoint of AB, for A(-3,3) and B(5,7)
Rufina [12.5K]

The y-coordinate of the midpoint, M of the segment AB described by; A(-3,3) and B(5,7) is; 5.

<h3>What is the y-coordinate of the point M which is the midpoint of AB, defined by; A(-3,3) and B(5,7).</h3>

It follows from the task content that the y-coordinate of the midpoint, M of AB defined by; A(-3,3) and B(5,7) is to be determined.

Hence, it follows from coordinate geometry that the y-coordinate of the midpoint is such that;

y = (y(1) +y(2))/2

y = (3 + 7)/2

y = 5.

Ultimately, the y-coordinate of the midpoint of AB; A(-3,3) and B(5,7) is; y =5.

What is the equation of a line parallel to the line y = 4x + 7 and passes through the point (3, 0)?
KATRIN_1 [288]
Two lines to be parallel their slopes have to be equal. 

so m1 = m = 4


y = mx + b ( Slope intercept form)


y = 4x + b

(3,0) is on the line:

0 = 12 + b

b = -12

y = 4x - 12

Graph the function.<br><br> f(x)=cos(x)−3
Lemur [1.5K]

See attachment for the graph of the function f(x) = cos(x) - 3

<h3>How to graph the function?</h3>

The equation of the cosine function is given as:

f(x) = cos(x) - 3

The above function is a cosine function, and the parent function of the cosine function is

f(x) = cos(x)

This means that the function f(x) = cos(x) is translated 3 units down to get the function f(x) = cos(x) -3

Next, we plot the graph of the function f(x) = cos(x) - 3

See attachment for the graph of the function f(x) = cos(x) - 3
