Answer:

y=-2x+7

Step-by-step explanation:

Hi there!

The form of slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

We are given the slope (-2) and a point (3,1)

We can immediately substitute -2 as the slope in the equation

y=-2x+b

Now we need to find b

Because the line will pass through the point (3,1), we can use it to solve for b

Substitute 3 as x and 1 as y

1=-2(3)+b

multiply

1=-6+b

add 6 to both sides to isolate b

7=b

Substitute 7 as b into the equation

The line is <u>y=-2x+7</u>

Hope this helps!

Answer:

C

Step-by-step explanation:

The slope m of the functions give the measure of the rate of change.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

g(x) = \frac{5}{2} x - 3 ← is in slope- intercept form

with slope m = \frac{5}{2} = 2.5

Calculate the slope of f(x) using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 3.5) and (x₂, y₂ ) = (1, - 1) ← 2 points from the table

m = \frac{-1+3.5}{1-0} = 2.5

Hence

The slopes of g(x) and f(x) are both m = 2.5, thus

The functions increase at the same rate → C
