Question 1011773: 1)Solve linear systems algebraically. Write the coordinates.
8x+5y=9
2x-5y=-1
2)The sum of two numbers is 36. Their difference is 24. Find the numbers.

Post one question at a time.

For number (3),the equation is given

in the form y = mx + b, where m is the slope

and b is the y-intercept.

The linear equation y = 6x - 7 has a

y-intercept at -7.

This means the graph of your equation

crosses the y-axis at the point (0, -7).
