Write the equation of the line that contains the following two points (0,-1)(1.3)

y=4x+1

Step-by-step explanation:

1. Find the slope using the slope formula and the ordered pairs.

Slope formula: y2-y1/x2-x1

3--1/1-0

= 3+1/1-0

= 4/1

Slope=4

2. Use the slope and one of the ordered pairs and put them into point-slope form

Point-slope: y-y1=m(x-x1)

M represents the slope and x1 and y1 represent the values in the ordered pair.

Let's use the pair (0,-1)

y+1=4(x-0)

3. Distribute 4 to x and 0 and subtract 1 from both sides to simplify the equation.

y+1=4x

y=4x-1

4. The equation is y=4x-1, which is written in y=mx+b form.

b( speed= same)

Step-by-step explanation:

because 4hr=26mi

1hr=26÷4

7 hr=7×26÷4=45.5
