Question

What is the answer to all these questions? I need help asap

Answer 1

Answer:

1: slope

2: y-intercept

1a: slope= 3

1b: 2

y=3x+2

2a: slope= -10

2b: 60

y= -10x+60

Step-by-step explanation:

Answer 2

Answer:

1) Slope= 2, y-intercept=4, equation: y=2x+4

2.Slope= -10 , y-intercept= 60 , equation: y=-10x+60

Step-by-step explanation:

Slope formula: $\frac{y_{2}-y_1 }{x_2-x_1}$

1. Plug in two sets of cordinates into the equation

(0,2) (2,8)

2. Solve, slope =2

3. Plug in one pair into the point slope formula

Point slope formula: $y-y_1=slope(x-x_1)$

4. y-8=2(x-2)

5.y-8=2x-4

6. y=2x+4

Do the same for the other equation
