True o r False: y = - 5x + 7 is the equation of a line that passes through the point (3,6) and has a slope of - 5.
1 answer:
Answer:
False
Step-by-step explanation:
The equation in slope-intercept form of a line is y=mx+b, where x and y can represent a point on the line by using the coordinates (x,y), m is the slope, and b is the y intercept.
To double check this equation, plug in the coordinates of the point (3,6) to make sure both sides of the equation equal to each other.
6 = -5(3) + 7
6 = -15 + 7
6 = -8
Because the equation is invalid, the line does not pass through these points.

Answer with explanation:
Presume that, initial water level to be, 0 mm, at a time t=0.
And water level is rising at the rate of .
After 6.2 years level of water will be =1.8 × 6.2
=11.16 mm
→Averge, that is increase in water level after 6.2 years is given by
→→Rate of Depreciating of water level is given by = Negative of Increase of water level=
