(b) Without drawing it, work out how many dots there are in Pattern 8.
Explain how you decide.

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula,equation,to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

Measures of the angle of r, 31 s (x+4) t (3x+9)

What is the slope of the line that contains the points (-5, 6) and (14. - 7)?
