Answer (<u>assuming it can be in slope-intercept form)</u>:

Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula
and substitute the x and y values of two points on the line into it. We can see that the line passes through (0,0) and (5,4), so let's use those points for the formula and solve:
So, the slope is
.
2) Next, identify the y-intercept of the line. The y-intercept is the point at which the line intersects the y-axis. We can see that the line intersects the y-axis at (0,0), so that must be the y-intercept.
3) Now, write the equation of the line in slope-intercept form using the
format. The number in place of
represents the slope, so substitute
in its place. The number in place of
represents the y-intercept, so substitute 0 in its place. This gives the following answer and equation:

I only could find part of the triangle sorry, but u1 is 2 radical 2
Answer:
0, 5/4
Step-by-step explanation:
If
, you get 0=0, which is obviously true.
As long as K is not 0, you can divide by k and get
which is solved by 
It’s in the 4th quadrant because the x value is 8 (positive ) so its on the right but the y value is -1 (negative) so it’s below the x-axis
