Answer:
Step-by-step explanation:
Given
Equations are
and 
take 

Put the value of y in another equation

Put the value of x in y

Hence,
To find the slope of a line, we must find the change in y values divided by the change in x values, given by the formula y2-y1/x2-x1 and represented by the variable m. We use our values from the ordered pairs to compute the slope, as follows:
m = (5-1)/(4-2) = 4/2 = 2
Therefore, the slope is 2. Because the slope is positive, this means that the line is rising.
