Answer:
The equation of the line that goes through points (1,1) and (3,7) is
Step-by-step explanation:
Determine the equation of the line that goes through points (1,1) and (3,7)
We can write the equation of line in slope-intercept form where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding Slope
Slope can be found using formula:
We have
Putting values and finding slope
We get Slope = 3
Finding y-intercept
y-intercept can be found using point (1,1) and slope m = 3
We get y-intercept b = -2
So, equation of line having slope m=3 and y-intercept b = -2 is:
The equation of the line that goes through points (1,1) and (3,7) is
Answer:
Step-by-step explanation:
So we know that:
To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:
Simplify:
And that's our answer :)
