Plss do #7 and #9 make sure to add why for brainliest :)

7. Function A has the greater initial value.

9. Function A is nonlinear.

Function B is linear.

Step-by-step explanation:

7. The initial value of a function is the same as the y-intercept, or the value of y when x equals 0. For function A, the y-intercept is 4.

Function B is written in slope-intercept form, y = mx + b, where b represents the y-intercept. So, the y-intercept of function B is 3.

Finally, let's compare the y-intercepts of both functions. 4 is greater than 3, which means that Function A has the greater initial value.

9. A function is linear when the change in y over the change in x is proportional.

Function A: Let's look at the graph of Function A. It has points at (0, -1), (1, 0), and (2, 3). From point (0, -1) to point (1, 0), the value of x and the value of y both increase by 1. However, from point (1, 0) to point (2, 3), the value of x goes up by 1 but the value of y goes up by 3. Since the increase in y is not proportional, Function A is nonlinear.

Function B: Function B is written in the form y = mx, where m represents the change in y over the change in x. For this equation, m = 1. This means that every time the value of x increases by 1, the value of y increases by 1 as well. This represents a proportional relationship, so Function B is linear.

the equation is not included but the answer is (1.50, 2.00, 2.75)

step-by-step explanation:

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points
