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

123

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 the equation and the slop intercpet form is

y=-2x+3

## Related Questions Write the equation in slope-intercept form of the line that has a slope of -2 and y-intercept of 2. The slope-intercept form of an equation is: y = mx + b Just copy down this equation, then replace "m" with the slope, and "b" with the y-intercept. The equation of the line is:Y = (put the slope in here) X + (put the y-intercept in here)   slope-intercept from is y=mx+b, m is the slope and b is the y-intercept. put the values of the slope and y-intercept into the equation. y=2x-2 The equation of the line is:Y = (put the slope in here) X + (put the y-intercept in here) Write the equation in slope-intercept form of the line that has a slope of 2 and contains the point (1, 1). Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (2, -8).  The equation of the line is:Y = (put the slope in here) X + (put the y-intercept in here)  The equation of a line written in slope intercept form has the form of y = mx + b. In this form, m is the slope of the line and b is the y intercept. slope intercept form is y=mx+b (m is slope, b is y intercept) slope = 4, y intercept = -2 y = 4x -2 It is part of the equation that intercepts the y axis For example the straight line equation: y = 2x+4 is in slope-intercept form and 4 is the y intercept and 2 is the slope. A straight line in slope-intercept format has the equation: y = mx + b Where m is the slope, b the y-intercept. So, all you have to do is copy this equation, then replace "m" by the given slope, and "b" by the given y-intercept.   y=-2x+3The equation I used was y=mx+b m is the slope and b is the y-intercept. In a slope intercept form of the equation of a straight line in the 2-dimensional coordinate plane.  The slope of x and the y intercept as for example in the straight line equation of y = 2x+3 the slope is 2 and the y intercept is 3  The slope/y-intercept form of a linear equation is y = mx + b, where m is the slope (&Atilde;&cent;&Euml;&dagger;&acirc;&euro;&nbsp;y/&Atilde;&cent;&Euml;&dagger;&acirc;&euro;&nbsp;x) and b is the y-intercept, the point where the line intersects the y axis. Therefore,y = 6x - 2 ###### Math and ArithmeticGeometryCalculusAlgebra Copyright © 2020 Multiply Media, LLC. All Rights Reserved.
