What is the equation of the line described below written in slope-intercept form? the line passing through point (2, 4), parallel to the line whose equation is y = x
if it helps, y = x can be written as y = 1x + 0.....here ur slope is 1. A parallel line will have the same slope
y = mx + b
slope(m) = 1
(2,4)...x = 2 and y = 4
now we sub and find b, the y int
4 = 1(2) + b
4 = 2 + b
4 - 2 = b
2 = b
so ur parallel equation is : y = x + 2
Answer: The required equation of the line in slope-intercept form is \(y=x+2.\)
Step-by-step explanation: We are given to find the slope-intercept form of the equation of a line passing through the point (2, 4), parallel to the line with the following equation :
\(y=x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\)
We know that
the slope-intercept form of the equation of a line with slope m and y-intercept c is given by
\(y=mx+c.\)
From equation (i), we have
\(y=x\\\\\Rightarrow y=1\times x+0.\)
Comparing with the slope-intercept form, we get
slope of line (i) is m = 1.
Since the slopes of two parallel lines are equal, so the slope of the new line will be
\(m=1.\)
Also, the line passes through the point (2, 4), so its equation will be
\(y-4=m(x-2)\\\\\Rightarrow y-4=1\times(x-2)\\\\\Rightarrow y-4=x-2\\\\\Rightarrow y=x-2+4\\\\\Rightarrow y=x+2.\)
Thus, the required equation of the line in slope-intercept form is \(y=x+2.\)
