Given:
points ( -6, -1)
x1 = -6
y1 = -1
Determine the equation of the line in slope-intercept parallel to y = 5x + 2
Equation for slope-intercept form:
y = mx + b
Solution:
The given line is already in slope-intercept form, hence we know that is equal to the slope, and since it is stated that they are parallel, that means that they have the same slope.
m = 5
Now in order to write the slope-intercept form of the given points, we must equate it first in point-slope form.
Point-slope form:
y - y1 =m (x - x1)
Substitute the given values of x1, y1, and m.
y - (-1) = 5(x - (-6))
y + 1 = 5(x + 6)
Distribute the value of 5 to each value inside the parenthesis, and transpose 1 on the other side of the equation, hence we must take note that in transposing a number, the sign changes.
y + 1 = 5x + 30
y = 5x + 30 -1
y = 5x + 29
Final answer:
Slope-intercept form: y = 5x + 29
