For perpendicular the way you find it is by flipping the fraction. and adding a negative. remember that whole number are fractions divided by 1.

so what you would get is

y=5x+a

then we put in the points into our x and y.

2=5(1)+a
now solve

2-5=a

a=-3

Now you will put into standard form

y=5x-3

Use the cross product property to solve each equation: 5/7 = x/9
enot [183]

Answer:

x = 45/7

Step-by-step explanation:

\frac{5}{7} =\frac{x}{9}

Here, you can more easily see what the fractions look like.

In order to cross-multiply, you have to multiply 5 with 9, and 7 with x.

45 = 7x

Then, you isolate x by dividing 7 on both sides:

45/7 = x

Hope I helped :)
