What is an equation of the line that passes through the points (0, -2) and<br> (0,-5)?
Nataly_w [17]

Step-by-step explanation:

The change in y-coordinate is -2 - (-5) = 3.

However, the change in x-coordinate is 0.

When the change in x-coordinate is 0, the graph is a vertical line.

Therefore the equation of the line is x = 0.

Hey can you guys help me please help
yawa3891 [41]
The triangle on the left area is 18 because the area of a triangle is 1/2 b times h so 12 times 3 times 1/2 equals 18.you then cut a triangle from the quadrilateral to make into a triangle.The triangle is the same height has other triangle so its area is 18.Since you took three for base of left and right triangle you subtract 6 from 1 to make it your base of 8 and your height is 12 and 12 tikmes  8 is 96 so 18+18+96=132 so our answer is 132.

Graph the line with: a slope of -5 and y intercept of 4. PLEASE HELP
worty [1.4K]

The y intercept of 4 means the graph crosses the vertical y axis at 4. More specifically this location is (0,4)

Start at (0,4) and move down 5 units and then move to the right 1 unit. You should arrive at (1,-1). The movement rule of "down 5, over to the right 1" is taken exactly from the slope of -5 = -5/1.

After plotting the two points (0,4) and (1,-1), draw a straight line through them both. Extend this line as far as you can in either direction. The graph is now completed.

<h3>In summary, this line goes through (0,4) and (1,-1)</h3>

Side note: The equation of this line is y = -5x+4. It is in slope intercept form.
