Given that y=mx+c, find the value of x when y=7, m=−2 and c=−7.
Question
Given that y=mx+c, find the value of x when y=7, m=−2 and c=−7.
Solution
To find the value of x, you can rearrange the equation y = mx + c to solve for x. The rearranged equation is x = (y - c) / m.
Substitute the given values into the rearranged equation:
x = (7 - (-7)) / -2 x = (7 + 7) / -2 x = 14 / -2 x = -7
So, when y = 7, m = -2, and c = -7, the value of x is -7.
