Answer:
y= -2x+9
Step-by-step explanation:
The equation will be written this way :
y= m*x+c
m is the slope c is a constant m =( f(4)-f(2))/(4-2)=(1-5)/2= -4/2 = -2 y = -2x+c replace x and y by the coordinates of a point to get c 1= -2*4+c c = 9 y = -2x+9
Answer:
y=-9/4.5+9
Step-by-step explanation:
To find the equation you do y=mx+b which means y= slope + y-intercept.
To get the slop you do rise over run which in this situation is 9/4.5. And the y-intercept is when the line touches the y-axis and in this problem it is 9. So the answer is y=-9/4.5+9
