The value of b is the y-intercept, which is the point where the graph crosses the y-axis. The number m is the slope of the line, where slope m = rise over run. It gives the steepness of the line. And of course, x and y are variables which change within the graph from one point to another.

the standard form of y = mx + b becomes y = 2x + b now you take the point (x,y) = (3,5) that is on the line (has to be on the line) and replace x and y in the equation with it. the equation becomes 5 = 2*3 + b then you solve for b. in this case b = 5-1 = -1 your equation becomes y = 2x - 1 graph of that equation looks like:

y = mx + B - Slope intercept form (y - Y1) = m(x - X1) - Point Slope form Example 1 Write the slope intercept form for the following equation using the given slope and point: slope = 12, point ( 3,1). Here are the steps to get the equation for this line: …

Question 1175153: If a line has an x-intercept at x = −7 and a y-intercept at y = −8, find its equation in the form y = mx + b. Answer by MathLover1(20826) ( Show Source ): You can put this solution on YOUR website!

y=(2/3)x+2 (this is it in y=mx+b form) to graph it you start at 2 on the y axis as one point and then go up 2 and to the right 3 and that is your second point then you make a line through it and there you go!

Express your answer in the form y=mx+b. (6,9); x+5y=6-----Hi, there--. Recall that parallel lines have the same slope. To solve this problem, we will rewrite the original equation in slope-intercept form to find the slope. Then we can use the point (6,9) to find the y-intercept for the parallel line. Then, presto! We'll have the equation..

Equation of AD is (y-y1) = m(x-x1) (y-6) = -1/2 * (x+4) 2y - 12 = -x - 4 2y = -x + 8 y= -1/2*x + 4 compare with y = mx + b m = -1/2 and b = 4 m+b = -1/2 + 4 = = 3.5. ANSWER If you really want to learn on how to solve such problems on your own, in …

You can put this solution on YOUR website! Write the equation for the following relation. E = {(x, y): (2, 15), (5, 30), (8, 45), . . .}

Question 530233: Given: m = (y2 - y1)/x2 - x1), y = mx + b, and the points (-2, 2) and (2, 4). Find the y-intercept. Write the equation of the line in slope-intercept form Answer by jim_thompson5910(35256) (Show Source):
