PLZZ HELP I HAVE A TIMER AND MORE QUESTIONS!! I WILL GIVE BRAINLEST On a coordinate plane, 2 lines are parallel to each other.
This system of equations has
1. Exactly one solution
2. No solution
3. Infinitely many solutions

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula, equation, to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

The parabola x = y² - 9 opens: a.)up b.)down c.) right d.)left

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function. a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
