Answer:
find -3 on the graph on the left side. and go four up from there
Step-by-step explanation:
THE SLOPE IS -2
if we have the coordinates of two points on a line, we can find the slope with this formula:

so the slope is

the answer is -2
good luck
To find the equation we will put the values of x and y in the equations and then check if LHS=RHS.
















Hence, Option B. y=5x+4 satisfies the system (1,9)
