Question 1171369
the general equation of a straight  line is y = mx + b
m is the slope
b is the y-intercept.
the graph crosses the y-axis at y = 1, therefore, the y-intercept is equal to 1.
the general equation becomes y = mx + 1.
the y-intercept is at the point (0,1)
the other point on the line is at the point (5,-1)
the change in y from the point (0,1) to the point (5,-1) is -2
the change in x from the point (0,1) to the point (5,-1) is 5
the slope is the change in y divided by the change in x = -2/5
the general equation becomes y = -2/5 * x + 1.
that's the equation of your line.
the graph of that equation is shown below:
