hello
to solve this question, let's find the y-intercept first.
y-intercept is the point at which the line passes through the y-axis
from careful observation of the graph, the intercept of this graph is equal to 5
intercept = 5
now let's pick two points and solve for the slope
the points can be (0,0) and (4, 5)

from the calculations above, the value of the slope is equal to 5 while the slope is equal to 5/4
