Question

How do you find slope, y- intercept, slope- intercept form, and point slope form for (-10,-17) (-8,-15.7)

Answer 1

Answer:

Slope = 0.65

y = 0.65x - 10.5

Step-by-step explanation:

Taking the points (-10,-17) and (-8,-15.7)

Slope = Change in y ÷ change in x

Change in y = -15.7 - -17 = 1.3

Change in x = -8 - -10 = 2

Slope = 1.3/2 = 0.65

Taking another point (x,y);

The slope intercept form is;

$\frac{y - -17}{x - -10}$ = 0.65

$\frac{y + 17}{x + 10}$ = 0.65

y + 17 = 0.65x + 6.5

y = 0.65x + 6.5 - 17

y = 0.65x - 10.5

Answer 2

Answer:

-10=x1 -17=y1

-8=x2 -15.7=y2

formula:

y2 -y1

_____ =m

x2-x1

y1=m(x1)+b
