Ya gotta use the Pythagorean theorem :)
a² + b² = c² (reminder: c is the hypotenuse)
4² + 8² = c²
16 + 64 = 80
√80 = 8.94
H = 8.94
Answer:
y = 2x + 7
Step-by-step explanation:
Find the slope with y2-y1/x2-x1, which is 2
Find y intercept, which is 7
Answer:
Step-by-step explanation:

1 over 3 should be the answer I think
The a value affects the graph by vertically stretching or compressing the graph.
The r and s values affect the zeros, or x intercepts of the parabola, and therefore the vertex.
Hope this helps!
