Answer:slope is the rise over run. so for the first one you have to go up 1 and over 3 then plot the point. the y intercept is the point on the vertical line. so you should then have two points the one on the vertical line and the rise over run.
Answer:Step-by-step explanation:6. if the slope is 8 , y-intercept is 2 use the general equation for slope intercept y= mx+b where m is slope and b is y-intercepty= 8x +2 7. slope is 0, y- intercept is -3y= 0*x -3 the equation is y= -38. (same steps for 9)slope is 5, and (2,7) on the lineuse the point slope equation (y-y1) = m( x-x1)y-7 = 5 (x-2)now transform it into the slope intercept form y= mx+by = 5x - 10 + 7; y = 5x -35. between the points (0, -2) and ( 2, 0 ) the slope is m = (y2-y1)/(x2-x1) =(-2-0)/(0-2) = 1, and the y-intercept is -2y= 1*x -2 ; y=x-213. a. y= 18x +10 because the distance y is 18 for each x hour plus the extra 10 miles that she had at the startb. the y-intercept is where the graph intersects the y-axis so is 10 and represents the starting point at 10 miles , and the slope is 18 and represents how fast is movingc. after 2 hours means x=2 y= 18*2 +10 = 36+10 = 46 miles
