The points (–9,s) and (–6,–10) fall on a line with a slope of –4. What is the value of s?

Step-by-step explanation:

We can set up an equation for this line using slope intercept form:

Where is the slope of the line and is the y-intercept (where the line cross the Y-axis at ).

We know that the slope of the line is so we can plug that in for , but we don't know , so we'll have to use the given point to help solve for it:

This means the equation of the line is . Now we can plug in the point and solve for :

you can't solve x because it is 2 linear equation and you only have one equation

40 x 50 = 2000
