I do not understand how to do this can you help me figure out the answer to the question

Y=4

Step-by-step explanation:

Yes,

a general equation of a linear equation in slope intercept form is

where m is the slope and b is the y intercept.

Since the answers are slope intercept form, we will eliminate some answers

y=2x and

y=-1/2x+1/2 is wrong becuase there slope isn't zero.

A slope of zero indicates we have a change of 0 in y axis/ over a infinite change of the x axis

Why isn't it the other way around.

Let look at this for an example

5/0 is undefined becuase we cant divide 0 by a number but

equal zero becuase anything that zero is divided by equal zero.

Back on track,we need find a answer we y will remain the same. The only answer is y=4 becuase all the answer on that line will have the same y values, but different x values.

x = 12

y = 15

step-by-step explanation:

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.
