Answer:the answer is 82 photo math helps a lot with these type of questions
Step-by-step explanation:
The y intercept is -2 because that’s where it crosses y axis
The slope is positive because the line goes upward from left to right
To calculate the slope look at this image. In that triangle rise is 2 and run is 4, so the slipe is 2/4=1.2
The answer is the second option
Answer:
13 degrees
Step-by-step explanation:
Triangles have to equal to 180 degrees
Answer:
y= x +4
Step-by-step explanation
ok slope intercept form is where we use two points to identify the slope of the curve:
the slope:
looking at the graph we can p[ick any two points to find the slope, I am going to use (-1,10) and (1,-3) since these are whole numbers and easier to see on the graph
next we use the slope formula which gives so is the slope, we can leave it as this fraction since it is easier than using a decimal.
now for the intercept
looking at the graph we can see that when x is 0 y is 4
so slope form is y=mx+b where m is the slope and b is the y intercept
this gives us y= x +4
To find the area of this rectangle you multiply the length by the width, like so (x+2) x (2x+5) .
To find the perimeter of this rectangle you add all the sides using this equation,
(x+2)+(x+2)+(2x+5)+(2x+5) .
