When the charge for 3 hours is $94 on Monday and $130 for 5- hour service on Tuesday would charge for 2-hour call service is $76.

Electricians charge a fixed rate + an hourly rate. The charges are a total of $94 for a 3-hour service call on Monday and $130 for a 5-hour service call on Tuesday.

How to solve the linear equation?

A linear equation is a one-degree equation. The equation includes the variable of the highest power one. The standard form of an equation is Ax + B = 0, where x is the variable, A is the coefficient and B is a constant.

To solve the linear equation we need to find the unknown variable which satisfied the given linear equation.

Electricians charge a fixed rate + an hourly rate

If he charges, $94 for a 3-hour call on Monday and $130 for a 5-hour call on Tuesday then charging for 2 extra hours is the difference between the two amounts.

130 - 94 = $36

for an hourly rate, it will be $18

For the fixed traveling charge, we will subtract the 3-hour rate from a fixed rate of $94 - 3 × $18 = $40

So, for x hour call the equation will be, 40 + 18x

for 2 hour service, the charges would be 40 + 18 × 2 = $76

Therefore, when the charge for 3 hours is $94 on Monday and $130 for 5- hour service on Tuesday would charge for 2-hour call service is $76.

The correct option is, (B) (2, –23).

What is called co-ordinate?

• Coordinates are distances or angles, represented by numbers, that uniquely identify points on surfaces of two dimensions (2D) or in space of three dimensions ( 3D ).
• There are several coordinate schemes commonly used by mathematicians, scientists, and engineers.

What is co-ordinate with example?

• A set of values that show an exact position.
• On graphs it is usually a pair of numbers: the first number shows the distance along, and the second number shows the distance up or down.
• Example: the point (12,5) is 12 units along, and 5 units up.

What is the co ordinate formula?

• One of the important formula of coordinate geometry is the equation of the straight line which is y = mx + c.
• Here m is the slope and c is the y-intercept (tan θ = m, here θ is the angle that the line makes with the positive x-axis).

What is coordinate of a point?

• The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane.
• Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis.
• The coordinates of a given point represent how far along each axis the point is located.
