Question

7x+8y= 8 Slope Y intercept

Answer 1

Answer:

$slope = - \frac{7}{8}$

y- intercept= 1

Step-by-step explanation:

Rearrange the equation such that it is in the form of y=mx+c. This form is known as the slope-intercept form, and m is the gradient while c is the y-intercept.

7x +8y= 8

8y= -7x +8

Divide by 8 on both sides:

$y = - \frac{7}{8} x + 1$

Thus, the slope is $- \frac{7}{8}$ and the y-intercept is 1.

Another way to find the y-intercept is to substitute x= 0 into the equation since the y-intercept occurs at x= 0.

7x +8y= 8

When x= 0,

7(0) +8y= 8

8y= 8

y= 8 ÷8

y= 1

Thus, the y-intercept occurs at y= 1 or the coordinate (0, 1).

Note: slope and gradient have the same meaning and can be used interchangeably

Answer 2

Answer:

Slope = -7/8

Y-intercept = (0, 1)
