Can someone explain this ? like explain how to do it

-2

Step-by-step explanation:

First, you have to find the slope.

Rise           1

  =    = 1

Run            1            

So, the slope is 1.

Next, if you write the graph in the slope intercept from, then it will be,

y=mx+b

y=1x+-3

We already know that x is 1 So,

y=1(1)+-3

y=-2

So, the answer is -2! Hope this helps!!!

When x = 1 ,  y = -2.

Step-by-step explanation:

I'm assuming you want the equation of this line.

The 2 points close together are (0, -3)  and (-1, -4).

Slope =  (y1-y2) / (x1 -x2)

= (-4-(-3)) / (-1 - 0)

=  -1 / -1 = 1

The  y-intercept is where y = -3.

The equation of a straight line is y = mx + c where m = the slope and c = the y-intercept, so the equation of this line is  y = 1x - 3

or y = x - 3 (the 1 may be omitted).

When x = 1, y = 1 - 3 = -2 (answer)

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.

answer: qc and de are congruent

hope i ! : )
