Question:
Consider the graph of the linear equation 2x-5y=10.
The x-intercept is .
The y-intercept is .. .
The slope is…
Answer:
Answer:
Slope-intercept form:
The equation of line is given by:
….[1]
where,
m is the slope and b is the y-intercept
Given the linear equation:
…..[2]
Subtract 2x from both sides we have;
Divide by -5 to both sides we have;
On comparing with [1] we have;
Slope(m) =
y-intercept(b) = -2
To find x-intercept:
Substitute y = 0 in [2] and solve for x:
⇒2x = 10
Divide both sides by 2 we have;
x = 5
x-intercept = 5
Therefore:
The x-intercept is 5
The y-intercept is -2
The slope is
