Answer:
12a - 6b
Step-by-step explanation:
Given
8a + 3b + 4a - 9b ← collect like terms
= (8a + 4b) + (3b - 9b)
= 12a + (- 6b)
= 12a - 6b
Answer:
Step-by-step explanation:
You would first need to find the slope. The Slope formula is m = (y2 - y1)/(x2 - x1). In your problem, (1, 2) could be (x1, y1) and (2, 5) could be (x2, y2). Substitute those values into the Slope formula to find m which is your slope.
The point-slope form of a line is y - y1 = m(x - x1). You already have (x1, y1) to substitute in so do that and also substitute in your m.
Answer:
y= x+ 3
