Let

we know that
The interior angles formed by the sides of a quadrilateral have measures that sum to 360°
so
°
therefore
the answer is
So in order to find the line you’ll have to submit the point (3,5) and the slope into the point slope formula : y-y1= m(x-x1)
Y-5= 1/3(x-3)
Solve(turn to y intercept form):
Y-5= 1/3x -1
3.75 miles per hr........in 2.5 hrs =
3.75 * 2.5 = 9.375 miles
1. a) Find the y-intercept of the line, then you find the slope the line, and then you can write the equation in y-intercept form, which is y=mx+b, m is the slope and b the y-intercept.
y= x+70 is the equation
b) 70
c) 120
