Answer:
y = -2x + 25
Step-by-step explanation:
A standard equation can be in slope-intercept form: y = mx + b
m is the slope, b is the y-intercept.
Plug in the given slope.
y = -2x + b
To find b, plug in the given point (9, 7).
7 = -2(9) + b
Multiply.
7 = -18 + b
Add 18 to both sides to find b.
25 = b
Plug this into your standard equation.
y = -2x + 25
Check by plugging in the given point again.
7 = -2(9) + 25
7 = -18 + 25
7 = 7
Your answer is correct!
Hope this helps!
