L has y-intercept (0, -3) and is parallel to the line with equation: y=2/3x+1?

Question

If you were graphing y = 2x, y=-x+3 and y=x+1 how would you graph these equation. Please explain Elementary I don’t understand how to graph. How would you feed this equation into a graph bar to graph it correctly?

46) Technology. Driving down a mountain, Tom finds that he has descended 1800 ft in elevation by the time he is 3.25 mi horizontally away from the top of the mountain. Find the slope of his descent to the nearest hundredth.



Write the equation of the line with given slope and y-intercept. Then graph each line using the slope and y-intercept. Slope: -2; y-intercept: (0, Slope: 5; y-intercept: (0, -2) Slope: -3/4 ; y-intercept: (0, 8)

Answer 1

1.) L has y-intercept (0, -3) and is parallel to the line with equation: y=2/3x+1?

To answer this, remember that parallel lines have the same slope. Since you're given the y-intercept, you can write the equation:
y = (slope)x + (y-intercept) = 2/3x - 3

2.) Driving down a mountain, Tom finds that he has descended 1800 ft in elevation by the time he is 3.25 mi horizontally away from the top of the mountain. Find the slope of his descent to the nearest hundredth.

Slope = rise/run
rise = -1800 ft
run = 3.25 mi * 5280 ft/mi = 17 160 ft

slope = -1800 / 17160 = -.10489... = -.10

For graphing, it's extremely hard to explain without actually being able to show you on a graph.

Answer 2

desires extra rationalization... in case you recommend, what line is parallel to y=2/3+a million with the intersect (0,-3)? the common equation is y=mx+b the place m=slope (the degree or steepness of a line) and the place b=y-intersect If the two traces are parallel, then they have the comparable slope. as a result, m=slope=2/3 b is the y-intersect, and (0,-3) is the (x,y) intersect, so -3=b=y-intercept. as a result, the line parallel to y=2/3x+a million with an intersect of (0,-3) is: y=2/3x-3
