For The Pairs Below Put Each Question In Slope Intercept Form And Whether The Graphs Of The Line Will

Answers

Answer 1
3: rearrange the 2nd equation so y is isolated, add 3x to both sides
Both equations are now y = 3x + 2. So they are identical, and therefore have infinite solutions since solution means how many times do these lines meet/overlap.

4: rewrite left-right and the equations are now:
y = -x
y = -x -2
Same slope but different intercept (b value), so they are parallel and NEVER meet (NO SOLUTIONS)

5. Rearrange:
y = -x + 4
y = x + 4

So they have different SLOPES in this example (m value). This means they are not parallel or identical, so they can only cross once (one solution)

6: rearrange both
y = 3x - 1
y = 3x + 1
Same slope (m=3), different intercepts (b= 1 and -1). Same slope means parallel, different b means different intercepts so they are NOT identical. Since parallel lines can not cross, there are no solutions

7: y = 2x + 4
y = 2x - 4
Same slope (m=2), different b values (y-intercepts are 4 and -4), so parallel but not identical, no solution

So the given angles are supplementary (add to 180). You take the two and add them. 21x+5+37x+1. This gets set to equal 180. 58x+6=180. Subtract 6 from both then divide by 58. You get x=3

While Roberto Clemente amassed a mountain of impressive statistics during his baseball career, he was often mocked by the print media in the United States for his heavy Spanish accent. Clemente was also subjected to the double discrimination of being a foreigner and being black in a racially segregated society. Although the media tried to call him "Bob" or "Bobby" and many of his baseball cards use "Bob," Clemente explicitly rejected those nicknames, stating in no uncertain terms that his name was Roberto. There was also confusion over the correct form of his surname. For 27 years the plaque at the National Baseball Hall of Fame read "Roberto Walker Clemente," mistakenly placing his mother's maiden name before his father's surname.
