Question

Can someone help me find the slope , y-intercept ,and equation pls help it’s my finals

Answer 1

Answer:

slope: -3

y-intercept: -5

equation: y = -3x - 5

Step-by-step explanation:

The formula for slope is:

(y2 - y1)/(x2 - x1)

Let's use these coordinates:

(-1, -2)

(0, -5)

x1 = -1

x2 = 0

y1 = -2

y2 = -5

Substitute into the formula:

(y2 - y1)/(x2 - x1)

(-5 + 2)/(0 + 1)

Solve:

(-5 + 2)/(0 + 1)

-3/1

= -3

slope = -3

The y-intercept is when the x coordinate is 0.

Looking at the table, we see the coordinate (0, -5).

The y-coordinate is -5.

This means that the y-intercept is -5

y-intercept = -5

Slope-intercept form:

y = mx + b

where m is the slope and b is the y-intercept

m = -3

b = -5

Substitute:

y = mx + b

y = -3x - 5
