y = -4x + 3 this line has slope = -4
parallel lines, slope is the same so slope of new line is also equal -4
passing thru (8, -3)
y = mx + b
b = y - mx
b = -3 - (-4)(8)
b = -3 + 32
b = 29
equation:
y = -4x + 29
hope it helps
3xy -6x
just multiply 3x by y and 3x by -2
The graph is showing the equation of circle x²+y²=4
<h3>What is a circle?</h3>
A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.
The given graph in the question represents the equation of the circle cutting the points on the x-axis and y-axis at 4 which is the radius of the circle.
The equation will be as follows:-
x²+y²=4
Hence the graph is showing the equation of circle x²+y²=4

The distance to be covered in the race is 25 miles
average speed of the team is 30 km/h
30 km/m in miles/hour will be:
1 mile=0.621371 km
thus
30 km/h=(30×0.621371) miles/hour
=18.64113 miles/hour
time taken to complete 25 miles will be:
time=distance/speed
=25/18.64113
=1.3411 hours
