Answer:
-10=x1 -17=y1
-8=x2 -15.7=y2
formula:
y2 -y1
_____ =m
x2-x1
y1=m(x1)+b
Step-by-step explanation:
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;
[tex]\frac{y - -17}{x - -10}[/tex] = 0.65
[tex]\frac{y + 17}{x + 10}[/tex] = 0.65
y + 17 = 0.65x + 6.5
y = 0.65x + 6.5 - 17
y = 0.65x - 10.5
