HELP ASAP i need too know these

Answer 1

Answer:

3. y = 4

4. y = 40

Step-by-step explanation:

3. To find y, input the value of 2 for x in the equation y = 3x - 2.

y = 3(2) - 2

y = 6 - 2

y = 4

y is 4 when x is 2.

4. To find the answer we first have to make an equation in y=mx + b form, where b is the y-intercept and m is the slope. We know that the y-intercept is -5 because the table tells us that when x is zero, y is -5. So, we can use the y-intercept and a point In this example I will use point (6, 13)) to find the slope:

Input the values you know into the equation:

13 = 6m - 5

Add 5 to both sides to isolate the 6m:

18 = 6m

Divide both sides by 6 to isolate the m:

3 = m

Our slope is 3. Now that we know the slope and y-intercept, we can make our equation:

y = 3x - 5

We can use this equation to find y when x is 15:

Input 15 in place of x:

y = 3(15) - 5

Solve:

y = 45 -5

y = 40

When x is 15, y is 40.

Hope this helps :)
