WebMay 10, 2024 · Explanation: Given: y = mx + b The objective is to have just 1 of b and for this to be on one side of the equals and everything else on the other side. To get b on its own subtract mx from both sides yd = dmx + bdddd → ddddy−mxd = dmx−mx +b dddddddddddddddddddddddddddddddddd.↓ ddddddddddddddd → ddddy − mxd = … WebMay 2, 2016 · How do you solve for x in y = mx + b? Algebra Linear Equations Multi-Step Equations with Like Terms 1 Answer Alan P. May 2, 2016 x = y − b m (with the obvious restriction m ≠ 0) Explanation: If XXXy = mx +b subtracting b from both sides XXXy − b = mx dividing both sides by m XXX y − b m = x flipping the sides (to make it look more normal)
Find the X and Y Intercepts of a Line Using Algebra
WebStep 2: Use the formula y = mx + b to determine the y-intercept, b. Replace x and y in the formula with the coordinates of one of the given points, and replace m with the calculated value, (2). y = mx + b If we use (1,3) and m = 2, we have 3 = 2 • 1 + b 3 = 2 + b 1 = b or b = 1 If we use the other point (3,7) and m = 2, will WebIn order to find the slope, it is simplest to put this line equation into slope-intercept form. If I rearrange this line to be in the form " y = mx + b ", it will be easy to read off the slope m. So I'll solve: 3 x + 2 y = 8 2 y = −3 x + 8 \small { y = -\dfrac {3} {2} x + 4 } y =−23x+4 pongthorn kitchawasuwan
Graphing linear equations using y = mx + b (Slope
WebApr 11, 2024 · Solution: The equation of the given function is: y = 4x^2 + ax + b. Using the y-intercept formula, we can find the y-intercept by substituting x = 0 in the equation and solving for y. y = 4 (0)^2 + a (0) + b = b. So the y-intercept is (0, b). But the problem says that the y-intercept of the given function is (0, 6). WebFeb 19, 2024 · If you just have a simple equation like y=mx+b, you would find the x-intercept by substituting 0 for y and solving for x. If it's a quadratic equation, you'd solve by either … WebNov 23, 2024 · After doing these plug-ins, you just solve the equation for b, finding that b = 4. That means that the y-intercept of the line = 4. Now let’s see how you can do the same problem, but a little bit faster. To do so, we first need to play around with the y = mx + b equation by subtracting the mx-term from both sides, like this: y = mx + b ... pongtorn phengnoi
