Can someone help me understand Slope-Intercept Form for algebra please???

Mathematics
1 answer:
Helen [10]2 years ago
5 0

Answer:

The slope-intercept form is simply the way of writing the equation of a line so that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are immediately apparent. Often, this form is called y = mx + b form. This form of a line is one of the most commonly used in algebra classes.

Help? Please?<br> I really suck at geometry

Answer:

x = 14

y = 4

Explanation:

Ok so, just from looking at the two triangles i can tell they're congruent right triangles. I used different colors to show which sides of the triangle correspond and are equal to each other in my attatched photo.

So the side thats equal to x is the same length as the side that's equal to y+10 on the other triangle.

So we can write the equation x = y + 10.

Using this same method, the side that's equal to x + 2 is the same length as the side that's equal to 4y on the other triangle.

So, we can write the equation 4y = x + 2.

Now we have the equations \left \{ {{x=y+10} \atop {4y=x+2}} \right. you could rewrite to be in slope- intercept form so they're easier to graph. But a graphing calculator online would plot it just fine.

If you graph these two equations they'll intersect at the solution ( 14, 4 ). I'll include the graph in my images as well.

To check your answer, you can plug in x and y and see if the triangle sides end up being the same length. I did and it was correct.

Determine the length of the missing side in each of the right triangles below using the Pythagorean Theorem: a2 + b2 = c2.
lara31 [8.8K]
The answer is 12
{13}^{2}  =  {5}^{2}  +  {b}^{2}  \\  {b}^{2}  =  {13}^{2}  -  {5}^{2}  \\ b {}^{2}  = 169 - 25 = 144
b =  \sqrt{144}  = 12


good luck
