Answer:

Step-by-step explanation:
All lines in the plane are of the form
y = mx+b
<u><em>The intersection with the Y-axis is obtained by replacing x with 0
</em></u>
<u><em>The intersection with the X-axis is obtained by replacing y with 0
</em></u>
If we want that the Y-intercept = -5, then
-5 = m(0)+b
So b = -5
Our temporal equation is then
y = mx-5
If we want that the X-intercept = 7, then
0 = m(7)-5
7m = 5
m = 5/7
So our final equation is

Any multiples of 4.5:1.5 would work because being proportional just depends on whether you can reduce to get the same answer of the first triangle. You could do anything like 9m and 3m or 27m and 9m
The equivalent to that is 8.
