Answer
• Line m: x = 3
,
• Line n: y = –4
Explanation
If a line has no y-intercept, it means it must be parallel to the y - axis. Thus, it is a vertical line that will only cross the x-axis once (in this case).
As we are given that the x-intercept is (3,0), then the equation of line m is:
Following the same logic, if a line has no x-intercept, it will be parallel to the x-axis and it will be a vertical line.
As we are given that the y-intercept is (0,-4), then the equation of line n is:

Answer:
y -2 = -2/3(x +4)
Step-by-step explanation:
There are several different forms of the equation for a line. Each is useful in its own way. Here, the line crosses the y-axis at a point between integer values, so using that intercept point could be problematical. That suggests the "point-slope" form of the equation for a line would be a better choice.
That form is ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
__
The two marked points are (-4, 2) and (5, -4). All we need is the slope.
The slope is given by the formula ...
m = (y2 -y1)/(x2 -x1) . . . . . . . . where the given points are (x1, y1) and (x2, y2)
m = (-4 -2)/(5 -(-4)) = -6/9 = -2/3
Using the first point, the equation for the line can now be written as ...
y -2 = -2/3(x -(-4))
y -2 = -2/3(x +4)
Answer:
I think his age is 39.
Step-by-step explanation:
If Cesar's age was 2 times Rosa's 6 years ago, that means their combined ages 6 years ago was 66. 66 dived by 2 is 33 and 33 plus the 6 years is 39.
