Answer:

Step-by-step explanation:
To find out the m(slope) of the equation use the formula:
.
Substitute the values:

Combine the values:

Find the value of the fraction:

M is -3.
The equation so far is 
To find the y intercept, substitute one pair of coordinates into the equation and solve for b:
.
We see that b =-17 so the full equation would be:
.
You would minus 5 by 45 giving you 40 then 40 divided by 35 but that would come out as a decimal 1.14.
is this all of the question?
Answer:
x = 7.5
y = 75
Step-by-step explanation:
if one angle of an equilateral triangle is 60 degrees (180/3) then 4x + 2x + 2x = 8x = 60, so x = 7.5
for y, we'll have to take the right triangle. we know that 2x = 15, and MON = 60, so 180 - 60 - 15 = 105.
180 - 105 will give us y, which is 75
