Answer: 12. 1.25 = slope
13. -1/2 = Slope
14. Take two points from the line on the graph and then use the slope formula, y2 - y1/x2 - x1 to get your slope.
15. Use the points in the equation y2 - y1/x2 - x1 to get your slope. Remember to simplify.
Step-by-step explanation:
12. = -6 - 9/ -8 - 4 = 1.25 = slope
13. =-10 - (-3)/9 - (-5) = -1/2 = Slope
Answer:
x = 6
Step-by-step explanation:
-5(-2) + [8(-2)/4] = 10+(-16/4) = 10-4 = 6
the equation is in x-terms, meaning is a vertical parabola, and therefore the axis of symmetry will be the x-coordinate of the vertex, namely x = -1.
The calculation is incorrect, because the slope is defined as
So, Emma has inverted numerator and denominator: she has calculated the inverse of the slope.
The correct calculation would be
