We have been given coordinate of a point (4,7). We are asked to find the equation of the line that has an undefined slope and passes through the given point.
We know that slope of a vertical line is undefined. So the vertical line passing through point (4,7) will have an undefined slope.
The slope of line will be undefined when x-coordinates of all points on the line are equal.
Since the line will have same x-coordinates for all y-coordinates, therefore, option B is the correct choice.
VUX : vertical line, undefined slope, represented by x = a number HOY : horizontal line, 0 slope, represented by y = a number
so we need an undefined slope.....that means it is a vertical line.....it is represented by x = a number......and that number is the one in the x position...so ur equation is : x = 4 (because (4,7)...the x digit is 4
A+B=15 —>A+15=B(plug this into the other equation) 60a+30b=600 60a+30(a+15)=600 60a+30a+150=600 90a+150=600 90a=450 A=5 (plug back in to first equation) A+B=15 5+B=15 B=10
What you can do in this case is the following rule of three to find the result: 1 light year ---> 5.88 * 10 ^ 12 miles 3.2 * 10 ^ 2 light year ---> x Clearing x we have: x = ((3.2 * 10 ^ 2) / (1)) * (5.88 * 10 ^ 12) x = 1.88 * 10 ^ 15 miles answer: In scientific notation, approximately it is 1.88 * 10 ^ 15 miles
