Answer:
y=-1/3x-5
Step-by-step explanation:
Find the slope(m), it is rise over run. this line doesnt "rise" per se; it goes down. You have to see at what rate. you find the rise with the y values. here you go from -3 to -7. the rise is -4 units. the run you find with the x values. here you go from -6 to 6. the run is 12 units. your rise over run is the fraction -4/12. This can be simplified to -1/3. Now you find the y-intercept(b). the graph intercepts the y axis at (0,-5). now you plug it into y=mx+b. y=-1/3x-5
