what is the x intercept
y = -5x+20
X intercept is where y = 0.
Insert value and calculate.
To find the x-intercept of the equation y = -5x + 20, we set y equal to zero and solve for x.
0 = -5x + 20
Now, let's solve for x:
5x = 20 (subtract 20 from both sides)
x = 4 (divide both sides by 5)
Therefore, the x-intercept is 4.
To find the x-intercept of a linear equation, you need to determine the value of x when y equals zero. In other words, the x-intercept is the point where the graph of the equation crosses the x-axis.
In the equation y = -5x + 20, we want to find the x-intercept, which is the value of x when y equals zero. To do this, we set y to zero and solve for x.
0 = -5x + 20
To isolate x, we subtract 20 from both sides of the equation:
-20 = -5x
Next, we divide both sides of the equation by -5:
(-20) / (-5) = x
Simplifying:
4 = x
So, the x-intercept of the equation y = -5x + 20 is x = 4. This means that the graph of the equation crosses the x-axis at the point (4, 0).
