Write an equation of the line below.
Lubov Fominskaja [6]

Answer (<u>assuming it can be in slope-intercept form)</u>:

y = \frac{4}{5} x

Step-by-step explanation:

1) First, find the slope of the line. Use the slope formula m = \frac{y_2-y_1 }{x_2-x_1} and substitute the x and y values of two points on the line into it. We can see that the line passes through (0,0) and (5,4), so let's use those points for the formula and solve:

m = \frac{4-0}{5-0} \\m = \frac{4}{5}

So, the slope is \frac{4}{5}.

2) Next, identify the y-intercept of the line. The y-intercept is the point at which the line intersects the y-axis. We can see that the line intersects the y-axis at (0,0), so that must be the y-intercept.

3) Now, write the equation of the line in slope-intercept form using the y = mx + b format. The number in place of m represents the slope, so substitute \frac{4}{5} in its place. The number in place of b represents the y-intercept, so substitute 0 in its place. This gives the following answer and equation:

y =\frac{4}{5} x+0\\y = \frac{4}{5} x

josh rented a truck for one day. there was a base fee of 20.99 and there was a additional charge of 86 cents for each mile drive
Harlamova29_29 [7]

Answer:

The drove the truck for 131 miles

Step-by-step explanation:

To get the number of miles travelled

Step 1: Subtract base fee from payment

133.65 - 20.99 = $112.66

If each mile costs 86 cents = $0.86

Step 2: Divide $112.66 by $0.86

112.66/0.86 = 131 miles
