Answer: y= 2x + 3
Step-by-step explanation:
Point slope formula: y = mx + b
Since the given point is (8,19), 19 is our y, and 8 is our x. Since the slope is 2, our m is 2.
Sub in values.
y = mx + b
19 = 2(8) +b
19 = 16 + b
b = 19-16
b = 3
Now that we have m and b, we can make the equation.
y = mx + b, sub in 2 for m and 2 for b
y = 2x + 3
19 = 2(8) + 3
19 = 16 + 3
19 = 19
So the answer is y = 2x+3
