What is the linear function equation represented by the graph?

graph of a line on a coordinate plane. the horizontal x-axis ranges from negative 5 to 5 in increments of 1. the vertical y-axis ranges from negative 5 to 5 in increments of 1. a line intersects the y-axis at begin ordered pair 0 comma 1 end ordered pair and passes through at begin ordered pair 4 comma negative 1 end ordered pair.

enter your answer in the box.

f(x)=

Y= -1/2x + 1

Step-by-step explanation:

The equation for a line is Y=Mx+B

M stands for the Slope.

 -Slope is rise/run. So, for this graph the line "rises" 1 point and "runs" left 2 points until meeting the line again. This slope is negative because it "runs" to the left.

B stands for the Y-Intercept

-The Y-intercept is the point at which the line crosses the Y axis. For this example, the line crosses the Y-intercept at (0,1).

i those same problems in math and dont know how to do them
