### What is the slope intercept equation of a line that has a slope of -2 and a y intercept of 3?

slop intercept form is y=mx+b where m is the slope. We have to find b. To do so we have to evaluate the problem. We see that the y-intercept is 3 which means the coordinate pair (x,y)=(0,3). Plug (0,3) into the question. it should like this 3=m(0)+b. now solve. anything times 0 is 0 so the equation is now 3=b. now we have m, which is -2 and b which is 3. plug it into…

### What is the rule for graphing lines when in y intercept form?

If you mean slope - y intercept form ... Y = mX + b, where b is the y intercept and m is the slope ... b is a point on the y axis --- 5 becomes the point (5,0). m is a slope best thought of as fraction. 3 becomes 3/1 ... to be used as 'rise' and 'run' ... rise tells how far to go up (if positive) or down (if negative)…

### What is the root of the equation m squared -6m -7 equals 0 found by completing the square?

To complete the square for a quadratic ax² + bx + c = 0 1) Divide through by the coefficient of the x² term to get x² + b/a x + c/a = 0; let B = b/a; let C = c/a; the equation is now x² + Bx + c = 0 2) Complete the square by taking half of B and adding it to x and squaring: (x + B/2)² 3) Expanding this…

### Can you find the equation of a line containing the given pair of points 3 2 and 9 3?

Assuming it's a straight line (y=mx+b or Ax+By+C=0) then we will: 1. Find the slope of the line using the slope formula. y2-y1/x2-x1=m (keep in mind that the bigger value does not necessarily have to be y2 or x2, you will end up with the same "m" value regardless) 2-3/3-9=m -1/-6=m 1/6=m 2. Calculate vertical shift (b value). Sub a point into the equation y=(1/6)x+b (It does not matter which point you use, again, either…

### What is the slope of y equals -6x-3?

A line expressed in slope intercet fom looks like this: y = mx + b where m is the slope (rise over run) and b is the place on the y axis where the line crosses. Your line crosses the y axis at -3 [point (0,-3)] Your line has a slope of -6. To plot your line, start at (0,-3) then move down 6 and right 1 to find your next point at (1,-9).
