To find the slope of a line, we will select to collinear points and input their values into the slope formula. Analyzing the graph, we see the points (10, 20) and (30, 30) directly intersect the graph. Now, we can calculate the slope:
Slope formula: m=y2-y1/x2-x1
Input the points (10, 20) and (30, 30) into the formula:
m=30-20/30-10
m=10/20
m=1/2
Therefore, the slope of the equation is 1/2.
