Answer:

$\large\boxed{-\dfrac{5}{8}+\dfrac{1}{4}=-\dfrac{3}{8}}$

Step-by-step explanation:

$-\dfrac{5}{8}+\dfrac{1}{4}=\dfrac{1}{4}+\left(-\dfrac{5}{8}\right)=\dfrac{1}{4}-\dfrac{5}{8}\\\\\text{find LCD:}\\\\8=2\cdot4,\ \text{therefore. LCD(4, 8) = 8}\\\\\dfrac{1}{4}=\dfrac{1\cdot2}{4\cdot2}=\dfrac{2}{8}\\\\\text{continuing}\\\\=\dfrac{2}{8}-\dfrac{5}{8}=\dfrac{2-5}{8}=-\dfrac{3}{8}$

Which of the following is the equation of a line in slope-intercept form for a line with slope = 5 and y-intercept at (0, -3)?

goblinko [34]

Answer

hello :

note : The equation of a linear function in point-slope form is : y – y1 = m(x – x1)

The point is A (x1 , y1)

Step-by-step explanation:

in this exercice : m = 5 x1 = 0 y1 = -3

the equation of a line in slope-intercept form for a line is :

y - ( -3) = 5 ( x - 0)

y +3 = 5 ( x - 0)
