Answer:

It is 6ft

Answer:

See attached photo for graph

Step-by-step explanation:

Solve the equation for y... (that means get y by itself)

4y = -5x - 6 (subtract 5x from both sides)

y = -(5/4)x - 6/4 (divide both sides by 4)

y = -(5/4)x - 3/2 (simplify)

Now you can graph using slope-intercept method. The y-intercept is -3/2, and the slope is -5/4

so you are going to use the Pythagorean theorem on the smaller triangle to find the connecting side's length

${5}^{2} = {3}^{2} ( {b}^{2} ) \\ b = 4$

now you can find the bigger triangle's hypotenuse

${6}^{2} + {4}^{2} = {c}^{2} \\$

c=4
