Write the linear equation -7x+8y=-1 in slope-intercept form

Question

need help in math bad

thank uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

Answer 1

slope-intercept form is y = mx + b

so -7x + 8y = -1 solving for y

add 7x to both sides

8y = 7x - 1

divide both sides by 8

y = 7/8x - 1/8

where m (slope) = 7/8 and y-intercept = -1/8

Answer 2

a bodybuilder weighs 140 lbs. he is gaining 2 lbs a week write a linear equation where y is the total weight and x is the number of weeks
