Answer:
Step-by-step explanation:
The slope-intercept form of a straight line is y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).
m is -9:
y = -9x + b
To find b, enter the one given point (1,-5)and solve for b:
y = -9x + b
-5 = -9*(1) + b
b = 4
The equation becomes y = -9x + 4
