x, 123
y, 258
Enter the answer as y=mx+c
what question?
y = 1x+135
y = 2x+12
y = 3x-111
or many other possibilities. A single point does not give much information.
To find the equation in the form y = mx + c given the values of x and y, you need to calculate the values of m and c.
To calculate m, which represents the slope of the line, you can use the formula:
m = (change in y) / (change in x)
In this case, the change in y is 258 - 123 = 135 and the change in x is 258 - 123 = 135, so the slope is:
m = 135 / 135 = 1
To calculate c, which represents the y-intercept (the point where the line crosses the y-axis), you can substitute the coordinates of one of the points (x, y) into the equation y = mx + c and solve for c.
Using the point (x = 123, y = 258):
258 = 1(123) + c
258 = 123 + c
c = 258 - 123
c = 135
Therefore, the equation of the line is y = 1x + 135 or simply y = x + 135.
