Question

What is the equation for this graph pls help me and pls make sure it’s right:))

Answer 1

Answer:

y = 5x + 4

Step-by-step explanation:

First I found the slope by using the the definition that slope is rise/run so I saw that the y value went up from 4 to 9 which is 5 units and then the x value went up one in that same time. This means that the slope is 5/1. Then I found the y intercept by seeing where x = 0. On the graph you can see the line touches the y - axis at a value of 4 which means that the y - intercept is 4. Plugging these values into the y = mx + b equation you get y = 5x + 4.

Answer 2

Answer:

y = 5x + 4

Step-by-step explanation:

Slope-intercept form uses the formula y = mx + b where m is the slope and b is the y-intercept.

The slope is 5, because from one point to another, you go up 5 and over one (5/1)

So you can substitute the slope into the formula:

y = (5)x + b

The y intercept is 4 because that is where the line crosses the y axis.

So substitute that:

y = (5)x + (4)

y = 5x + 4
