Answer:

To write an equation for a line, you can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).

To find the slope of a line given two points, you can use the following formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Using this formula, you can find the slope of Line A by plugging in the coordinates of the two points:

m = (14 - 4) / (6 - 1) = 10/5 = 2

You can then use the slope-intercept form of a linear equation to write the equation for Line A:

y = 2x + b

To find the y-intercept, you can plug in the coordinates of one of the points (1, 4) and solve for b:

4 = 2 * 1 + b

b = 2

The equation for Line A is therefore:

y = 2x + 2

You can use the same process to find the equation for Line B. The slope of Line B is:

m = (23 - (-2)) / (6 - 1) = 25/5 = 5

Using the slope-intercept form of a linear equation, you can write the equation for Line B as:

y = 5x + b

To find the y-intercept, you can plug in the coordinates of one of the points (1, -2) and solve for b:

-2 = 5 * 1 + b

b = -7

The equation for Line B is therefore:

y = 5x - 7
