What is the equation for the coordinates (-1,1) and (24,-24)

Answer 1

Assuming we're talking about a straight line, the general equation is:

y = mx + b

where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis). So to find the equation of the line that goes through the two given points, we need to find the values of m and b. To find the slope, m, we use the slope formula which you can look up on line or in your text book:

m = (y₂-y₁) / (x₂-x₁)

where (x₁,y₁) and (x₂,y₂) are the two given points on the line. Plug the x and y values of the two points you are given into the formula to find the slope. It doesn't matter which point you choose for (x₁,y₁) and (x₂,y₂).

Once you have the slope, put the value into the general equation above in place of the m. Now to find the y-intercept (b), simply plug in the x and y values of either of the two given points into the equation and solve for b.
