Q. The equation for line f can be written as y=2x+3. Line g is parallel to line f and passes through the point (5,6). What is the equation of line g ?
Identify slope of line f: Identify the slope of line f. The equation of line f is given as y=2x+3. The slope-intercept form of a line is y=mx+b, where m is the slope and b is the y-intercept. By comparing the given equation with the slope-intercept form, we can see that the slope (m) of line f is 2.
Determine slope of line g: Determine the slope of line g. Since line g is parallel to line f, it will have the same slope. Therefore, the slope m of line g is also 2.
Use point to find y-intercept: Use the point (5,6) to find the y-intercept (b) of line g. We know that line g passes through the point (5,6) and has a slope of 2. We can use the point-slope form of the equation of a line, which is y−y1=m(x−x1), where (x1,y1) is a point on the line. Plugging in the values, we get: 6−y1=2(5−x1) Since (x1,y1) is (5,6), we have: (b)1 This simplifies to: (b)2 This equation is true, but it does not help us find the y-intercept. We need to use the slope-intercept form (b)3 to find (b)4. Let's plug the point (5,6) into this form: (b)6(b)7 Now, we solve for (b)4: (b)9g0
Write equation of line g: Write the equation of line g.Now that we have the slope m=2 and the y-intercept b=−4, we can write the equation of line g in slope-intercept form:y=2x−4
