How do you find slope, y- intercept, slope- intercept form, and point slope form for (-10,-17) (-8,-15.7)
2 answers:
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;
= 0.65
= 0.65
y + 17 = 0.65x + 6.5
y = 0.65x + 6.5 - 17
y = 0.65x - 10.5
