Web10 mei 2024 · How do you find the x and y intercept of x + 4y = 8? Algebra Graphs of Linear Equations and Functions Intercepts by Substitution 1 Answer ali ergin May 10, 2024 x-intercept: 8 y-intercept: 2 Explanation: we write y=0 to find x-intercept . x + 4y = 8 x + 4 ⋅ 0 = 8 x + 0 = 8 x = 8 we write x=0 to find y-intercept . x + 4y = 8 0 + 4y = 8 4y = 8 WebIf the x-intercept is 4 then y= 0 when x= 4 so 0= 4a+ b. If the y intercept is 8 the y= 8 when x= 0. 8= 0a+ b= b. Since b= 8, 0= 4a+ 8. Subtract 8 from both sides to get 4a= -8. Divide …

WebQuestion: x<-8, postive for x>-8, and has a y-intercept of 4. x<-8, postive for x>-8, and has a y-intercept of 4. Expert Answer. Who are the experts? Experts are tested by Chegg as … Web23 nov. 2016 · If we know the X-Intercept and the Y-Intercept, then we have two points. With two points, we can define the slope of the line and, indeed, an equation for the line through those two points. Using your example, suppose the X-Intercept is 8 and Y-Intercept is 11. Then we know that ( 8, 0) and ( 0, 11) are points on this line. cvs pharmacy brayton point somerset ma

Weby-intercepts are when the line touches the y-axis. To find these, find the y when x = 0. The point for a y-intercept will look like (0,y) x-intercepts are when the line touches the x-axis. To find these, find the x when y = 0. The point for an x-intercept will look like (x,0) ( 4 votes) Samantha 6 years ago Web1 mrt. 2015 · 4. To find the y-intercept (b), you need to set x to one of the x values and y to one if the y values and solve: y=mx+b b=y-mx. The function could look like this: m=getSlope (x1,y1,x2,y2) b=y1-m*x1 return b. The coordinates of the point would be (0,b), so you can return that instead if you want. Share. Improve this answer.
