Which line has an equation of y=-5x+4 in slope-intercept form?
-a line passing through the points (1,9) and (3, 19)
-a line passing through the points (2, -14) and (4, -24)
-a line passing through the points (1, 1) and (3, 11)
-a line passing through the points (2, -6) and (4, -16)

Last choice.

Step-by-step explanation:

To find the option that is equivalent to this equation, we can begin by narrowing down our options. The slope contains a negative number, meaning the second point must have a lower y value than the first.

Using this criteria, we can eliminate the first and the third answer. Now, we can test the second and fourth answer.

We can test using the slope formula and plugging in values. When the slope formula:

We get a slope of -5 for both of these equations. Let's plug in the point values to check whether they work:

Choice 2:

-24 = -5(4) + 4

-24 = -20 + 4

-24 ≠ -16

Choice 4:

-16 = -5(4) + 4

-16 = -20 + 4

-16 = -16

Therefore, choice 4 is correct!

4 hours

Step-by-step explanation:

this is because 1/5 hours equals 1/20 lawn so 1 hour equals 1/4 lawn and 4 hours equals whole lawn
