write as follow
x = 0:100;
m = 3;
c = 4;
y = m * x + c;
plot(x, y)

The problem is that in order to plot the equation you need to have 3 known values and one unknown value because there 4 values in equation x, y, m and c. So you should atleast have three values or if you just plot some random values of x and y and then want to find m and c then using cftool is the best option

If you are given values of x and y then you can compute m and c as follow:
fitvars = polyfit(x, y, 1);
m = fitvars(1);
c = fitvars(2);

>>syms x y m c
>> solve(' y = m * x + c')
i think this gone solve your question, if it is solved accept the answer
