What is the equation of the line that passes through (4,6) and (4,-4)

The slope is undefined, no equation

Step-by-step explanation:

Use the given points to solve for the slope.

The slope is undefined because a number cannot be divided by 0.

This means that the line is a vertical line at the x-intercept, and an equation cannot be found because we need a slope to solve the point-slope formula.

The line is at 4 on the x-axis because that is the number given for the x in each point.

y -y = m(x - x)

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
