What is the equation in slope-intercept form of the line that passes through the point (5,0) and is parallel to the line represented by y = 1.2x + 3.8?

Answers

Answer:

y=1.2x-6

Step-by-step explanation:

place in the points

0=1.2(5)+b

distrubutive property

0=6+b

subtract 6 on both sides

-6=b

y=1.2x-6

The equation in the slope-intercept form of the line that passes through the point (5,0) and is parallel to the given line is y=1.2x-6.

The given equation is y = 1.2x + 3.8.

We need to find what is the equation in the slope-intercept form of the line that passes through the point (5,0).

What is the slope-intercept form?

The slope-intercept form of a straight line is used to find the equation of a line. For the slope-intercept formula, we have to know the slope of the line and the intercept cut by the line with the y-axis. Let us consider a straight line of slope 'm' and y-intercept 'b'. The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as y= mx+b.

Now, the line of the equation that is parallel to y = 1.2x + 3.8.

Here, m1=1.2

The slopes of parallel lines are equal and the formula for the slope of parallel lines is m1 = m2.

Then, m2=1.2

Now, put m=1.2 and the point (5,0) in y=mx+b

That is, 0=1.2×5+b

⇒b=-6

The equation of the line is y=1.2x-6

Therefore, the equation in the slope-intercept form of the line that passes through the point (5,0) and is parallel to the given line is y=1.2x-6.
