Answer:
The first graph.
Step-by-step explanation:
The graph of the function y = 2x + 7, is a straight line because it is a linear function, and has y-intercept of 7 and a slope of 3; so we are looking for a graph that has these characteristics.
From the 4 graphs, we see that the 1st graph has a slope of 3 and a y intercept of 7, and thus it is the correct answer.
Answer:
the answer is-
Step-by-step explanation:
160,170,180,190
Answer:
-13/3
and the last 2
Step-by-step explanation:
The rational numbers include all the integers, plus all fractions, or terminating decimals and repeating decimals. Every rational number can be written as a fraction a/b, where a and b are integers. For example, 3 can be written as 3/1, -0.175 can be written as -7/40, and 1 1/6 can be written as 7/6.
Answer:
The expressions include:
6x - 5
3x - 5 + 3x
-2x - 5 + 8x
Step-by-step explanation:

Hey there! :)
-7x - 4y = -8
To find the slope, we must turn this equation into slope-intercept form.
Slope-intercept form is : y=mx+b ; where m=slope, b=y-intercept
To get here, we must isolate y by adding 7x to both sides of our original equation.
-7x + 7x - 4y = 7x - 8
Simplify!
-4y = 7x - 8
Then, divide both sides by -4.
-4y ÷ -4y = (7x - 8) ÷ -4y
Simplify!
y = -7/4x + 2
Congrats, we got y isolated! Now, review the slope-intercept form equation to figure out what our slope & y-intercept are.
After reviewing our slope intercept form equation, we can come to the conclusion that -7/4 is our slope because it's in the "m" value slot, and 2 is our y-intercept because it's in the "b" spot.
So, our answer is :
Slope = -7/4
Y-intercept = 2
Hope this helped! :)
