x-intercept is where the line intersects the x-axis. This would be point (-250, 0). It will be marked in pink in the image below.
y-intercept is where the line intersects the y-axis. This would be point (0, 100). I will be marked in green in the image below.
Hope this helped!

We assume the triangle is a right triangle. In a 30°-60°-90° triangle, the longest side is twice the length of the shortest.
... 4x = 2(√(x/2))
... 2x = √(x/2) . . . . . . divide by 2
... 4x² = x/2 . . . . . . . . square both sides
... 8x² - x = 0 . . . . . . . multiply by 2, subtract x
... x(8x -1) = 0 . . . . . . . factor
... x = 0 . . . or . . . x = 1/8 . . . . . . values of x that make the factors zero
The first case (x=0) is a "degenerate" case and is not useful. The entire triangle is a single point in that case.
The value of x is ...
... x = 1/8
Answer:
y = x - 1
Step-by-step explanation:
Since we already know the slope, we need to find the y - intercept.
We plug in the x and y coordinates that we know and slope into the equation to find y intercept.
Once we know this, we can replace the b and m in the y = mx + b and that is the equation of the line.
Answer:
y= -2/5 x -4
Step-by-step explanation:
So the equation is y=mx+b. Where m=slope and b=y-intercept. To find b, you would see at what point does the line cross the y axis. That would be at -4 so, -4 would be the b or y-intercept. To find m, you would take two points on the line and use this equation:
m=(y2 - y1 )/(x2 - x1)
If you were using the points, (-10,0) and (0, -4) the equation would be:
m=(-4-0) / (0+10)
So, m= -2/5
The equation of the line would end up being:
y= -2/5 x -4
