Determine the y-intercept, b, of the additive relationship y=x+7. Write as an ordered pair.(1 point) Responses The y-intercept is 7 and is represented by the ordered pair (0,7). The y -intercept is 7 and is represented by the ordered pair left parenthesis 0 comma 7 right parenthesis . The y-intercept is −7 and is represented by the ordered pair (−7,0). The y -intercept is negative 7 and is represented by the ordered pair left parenthesis negative 7 comma 0 right parenthesis . The y-intercept is −7 and is represented by the ordered pair (0,−7). The y -intercept is negative 7 and is represented by the ordered pair left parenthesis 0 comma negative 7 right parenthesis . The y-intercept is 7 and is represented by the ordered pair (7,0). The y -intercept is 7 and is represented by the ordered pair left parenthesis 7 comma 0 right parenthesis .
The correct response is:
The y-intercept is 7 and is represented by the ordered pair (0,7).
Use the table to answer the question. x y −2 −9 −1 −8 0 −7 1 −6 2 −5 Find the y-intercept and write it as an ordered pair (a coordinate point). (1 point) Responses The y-intercept is 7 and is represented by the ordered pair (7,0). The y -intercept is 7 and is represented by the ordered pair left parenthesis 7 comma 0 right parenthesis . The y-intercept is 7 and is represented by the ordered pair(0,7). The y -intercept is 7 and is represented by the ordered pair left parenthesis 0 comma 7 right parenthesis . The y-intercept is −7 and is represented by the ordered pair (0,−7). The y -intercept is negative 7 and is represented by the ordered pair left parenthesis 0 comma negative 7 right parenthesis . The y-intercept is −7 and is represented by the ordered pair (−7,0).
Looking at the table, we can see that when x = 0, y = -7. So the y-intercept is -7.
The correct response is:
The y-intercept is -7 and is represented by the ordered pair (0,-7).
You were born 2 years before your sister. Write the equation of the additive relationship where x is your age and y is your sister’s age.(1 point) Responses x=y+2 x equals y plus 2 x=y−2 x equals y minus 2 y=x−2 y equals x minus 2 y=x+2
The correct response is:
y = x + 2
It takes you 15 minutes longer to walk to school than your best friend. Write an equation that represents how long it takes you to walk to school.(1 point) Responses x=y−15 x equals y minus 15 y=x+15 y equals x plus 15 y=x−15 y equals x minus 15 x=y+15
The correct response is:
y = x + 15
A skating rink charges you $10.00 to enter the rink and then $1.00 for each hour you play. Write an equation that represents the total cost, y, you will pay based on the number of hours you spend at the skating rink. Let x represent the number of hours you play.(1 point) Responses y=x+10 y equals x plus 10 x=y−10 x equals y minus 10 x=y+10 x equals y plus 10 y=x−10 y equals x minus 10
The correct response is:
y = x + 10
