Answer:
The correct option is B) .
Step-by-step explanation:
Consider the provided information.
Mike's age is five more than three times his sister's age. Mike is seventeen years old.
Let Mike's sister age is x.
Five more than three times his sister's age can be written as:
Mike is seventeen years old.
Hence, the required equation is .
Thus, the correct option is B) .

Answer:
y = 4x + 14
Step-by-step explanation:
slope-intercept form: y = mx + b
Slope formula:
To write the equation in y = mx + b form, we need to find the slope(m) and the y-intercept(b) of the equation.
To find the slope, take two points from the table(in this example I'll use points (0, 14) and (1, 18)) and input them into the slope formula:
Simplify:
18 - 14 = 4
1 - 0 = 1
The slope is 4.
To find the y-intercept, input the values of the slope and one point(in this example I'll use point (1, 18)) into the equation format and solve for b:
y = mx + b
18 = 4(1) + b
18 = 4 + b
14 = b
The y-intercept is 14.
Now that we know the slope and the y-intercept, we can write the equation:
y = 4x + 14
