Step-by-step explanation:
<u>Slope intercept form:</u>
- y = mx + b, where m - slope, b - y-intercept
<u>Take two points from the graph:</u>
<u>Find the slope:</u>
- m = (3 - 1)/(3 - 1) = 2/1 = 2
<u>Find the y-intercept using point (2, 1) and the equation above:</u>
- 1 = 2*2 + b
- b = 1 - 4
- b = -3
<u>The line is:</u>
Answer:
Step 2
Step-by-step explanation:
Fiona did mistake step 2.
Use the distributive property to multiply -3 times each term in the trinomial.
The correct result is
-3(5x^2 - 2x + 7) = -15x^2 + 6x - 21
Fiona written -6x instead of + 6x.
That's the error.
The answer is "Step 2"
Hope you will understand the concept.
