Question

Please help me with this question

Answer 1

to answer this question you need to solve for the y values

to solve for the y values you plug in the x on the right side of the table and into the equation: -4x+3 and see if the y value given is the correct value

so lets start with the first option:
1. plug in your x value: -4(-1)+3
2. multiply: 4+3
3. add: 7
4. does the y value match? no

second option:
1. plug in your x value: -4(-3)+3
2. multiply: 12+3
3. add: 13
4. does the y value match? no

third option:
1. plug in your x value: -4(0)+3
2. multiply: 0+3
3. add: 3
4. does the y value match? yes

fourth option:
1. plug in your x value: -4(2)+3
2. multiply: -8+3
3. add: -5
4. does the y value match? no

so your answer has to be the third option!

Answer 2

For this question, you simply take the x value from the given chart and plug it into the equation, then if the outcome makes sense based on the chart then you use another value of x and plug the second value in and if that also makes sense then you continue plugging in all the x values from the chart until all of them match. There is only one chart which contain the correct table of values.

To start of, let’s plug in the x values from graph 1, the first two values seems to be correct. However, in the third value, it does not match, therefore the first option is in correct.

Moving on to the second option, we could already determine that this table of values is incorrect because the very first x value does not match.

Moving onto the third table of values, we determine that all of the x values are in accordance with the y-values, therefore this option is correct.

Answer: Third option
