Question 206373: what do the variables in the equation y=mx+b mean? Answer by ... b=y int y=variable on ...

The x and y are coordinates of a point on a rectangular coordinate system. So let's say m=2 and b=1 Then at x=1 y=mx+b=2*1+b=3 Then at x=0 y=2*0+1=1. Using these two points you can plot a line as shown below and note the slope of 2 (one unit to the right means two units up) and y-intercept=b=1 at x=0 or at point (0,1):

Y=mx+b, where m and b are real numbers and are not equal to zero. D: R: Answer by solver91311(24713 ...

The slope-intercept form is: y = mx + b. m = slope m = rise over the run m = change in y / change in x m = 0 if the line is horizontal m = undefined if the line is vertical b = y-intercept y-intercept is the point (0, b). In your given equation: y = 4 y = (3/5)*x + b so 4 = (3/5)*x + b m = 3/5 This means that y changes 3 units when x changes 5 ...

Suppose that the line with equation y=mx+b passes through the points (4,5) and (3,-1) Then m+b=?. m is just the slope between the two points: m = (y2-y1)/(x2-x1) m = (-1-5)/(3-4) m = -6/-1 m = 6. to find b, plug one point (4,5) and the slope into equation: y=mx+b 5=6(4)+b 5=24+b-19 = b. So, m+b = 6-19 = -13

Question 341887: I have a question about the equation, "y=mx+b" Why is "m" the slope, and why is "b" the intercept? Please explain specifically. Thank you. Found 2 solutions by Alan3354, Edwin McCravy:

Write the equation in the form y = mx + b. Through (−5, 1), slope −4 Algebra -> Inequalities -> SOLUTION: Find the equation of the line satisfying the given conditions.

Find the slope of the line. Do that by putting the equation in slope-intercept form, y = mx + b. That means solve for y. 9x+3y = 36 3y= - 9x + 36 y = -3x + 13 The slope, m = -3-----The slope of lines parallel have the same slope. The slope of lines perpendicular is the negative inverse, m = +1/3-----Use y = mx + b and the point (1,2) to find b ...

Express your answer in the form y=mx+b (5,-7); 7x+2y=3 Algebra -> Coordinate Systems and Linear Equations -> SOLUTION: Write an equation of the line containing the given point and parallel of the given line.

y = 0.22 x + -0.89 Compare this equation with y=mx+b slope m = 0.22 The slope of a line parallel to the above line will be the same The slope of the required line will be 0.22 m= 0.22 ,point (-6,7) Find b by plugging the values of m & the point in y=mx+b 7=-1.33+ b b=8.33 m=0.22
