The slope-intercept form:

y=mx+b

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-4, 47) and (2, -16). Substitute:

m=\dfrac{-16-47}{2-(-4)}=\dfrac{-63}{6}=-\dfrac{63:3}{6:3}=-\dfrac{21}{2}

Therefore we have:

y=-\dfrac{21}{2}x+b

Put the coordinates of the point (2, -16) to the equation:

-16=-\dfrac{21}{2}(2)+b\\\\-16=-21+b\qquad\text{add 21 from both sides}\\\\5=b\to b=5

Answer: \boxed{y=-\dfrac{21}{2}x+5}

Consider the line y=5/7x+7. Find the equation of the line that is parallel to this line and passes through the point (-5,-2). Fi
butalik [34]

Step-by-step explanation:

m=5/7

m1=m2=5/7

L;y-(-2)=5/7(x-(-5)

y+2=5/7(x+5)

7y+14=5X+25

7y-5x=11 is parallel lines

m1*m2=-1 is perpendicular lines

m2=-1*7/5

m2=-7/5

L;y+2=-7/5(x+5)

5Y+10=-7x-35

5y+7x=-45 is perpendicular lines
