Randolph is trying to find the equation of a line parallel to y = x − 6 in slope-intercept form that passes through the point (−
bekas [8.4K]
An equation of a line parallel to y=x-6, must have the same slope.

In this equation:
y=mx+b                        (slope-intercept form)
m is the slope:

The slope of the equation y=x-6 is m=1  (the number beside "x").

Now we have a point (-1,5) and the slope m=1.

Point-slope form of a line:
y-y₀=m(x-x₀)
so:
y-5=1(x+1)

answer: the equation of the line in point-slope form is :
y-5=1(x+1)

And the eqution of this line in slope-intercept form is:
y=x+6

y-5=(x+1)
y=x+1+5
y=x+6

the base of a ten foot ladder stands six feet from a house. How many feet up the house does the ladder reach
Ludmilka [50]
In this problem you will need to use the Pythagorean theorem (c^2=a^2+b^2).
The a and b represents the two edges, while c is the diagonal side and it is called the hypotenuse. Since you already know what the hypotenuse is and what one of the sides already are you just have to use the problem: c^2-a^2=b^2. Then if you plug the data you already have into the problem you will get 10^2-6^2=b^2. That then equals 100-36=b^2. Then you subtract and get b^2=64. Then you square root both sides and you get the answer b=8.
