Answer:
y = 15x - 10
Step-by-step explanation:
slope is given: 15
(x, y) is given: (1, 5)
plug values into y = mx + b:
5 = (15)(1) + b
solve for b:
b + 15 = 5
b = -10
rewrite the equation:
y = 15x - 10
Find x-intercept and y-intercept
x-intercept = 3 → (3, 0)
y-intercept = -6 → (0, -6)
The formula of a slope:

Answer:
2√5
Step-by-step explanation:
The side ratios in a 30-60-90 triangle are ...
1 : √3 : 2
The longest side (x) is 2 times the length of the shortest side (√5), so ...
x = 2√5
